Re: When Google Chrome runs, I see 100% CPU usage! Google Chrome Guide 10/29/08 6:01 PM
This issue should be fixed in the latest release of Google Chrome. If you're running a version earlier than 0.3.154.6, please update.

If you're still running into problems, update this thread with a few details:

- What version of Chrome do you have?
- What operating system are you running? Please include as many specifics (like service packs) as you can.
- What hardware are you running? How fast is your processor? Is it single or dual core?
- What other software are you running? Do you notice any mysterious processes in your Windows Task Manager?

Thanks!

Simon

Thanks for staying on top of this guys.

Prior to this update you tube videos would play for the first 3 or 4 seconds after intensive browser use and then just stop. I'll see if I still have the same problem and report back.

Chrome 0.3.154.9
Windows XP SP3 32bit
2.1 GHz Dual Core AMD Turion X2 Ultra
No mysterious software / no anti-virus either

Hey steveXstevo,

Thanks for the report. Not being able to use multiple tabs of streaming video is no good. Can you follow up by filing a crash report? I've included the link of where to do so below. If we can see a minidump it will be much easier for us to track down exactly what's happening. Fill out the form with the info you used here and then attach any relevant files.

Thanks,
Maggie

Hey steveXstevo,

Just a heads up - we got your minidump and we'll be in touch with you if we have more information.

Re: When Google Chrome runs, I see 100% CPU usage! jmcgill 11/6/08 4:19 PM
Hi all,

Running 3.154.9 and still getting 100% CPU if I leave my browser open for too long.

Windows task manager and Chrome task manager both show Chrome as only using ~30% CPU with Shockwave being responsible for 10 - 20% of that however both cores on my Core 2 Duo laptop are maxed out at 100%. Killing shockwave usually solves this. Killing chrome ALWAYS solves this. I have a tendency to leave tabs open for a long time. I *always* have gmail open, which means that flash is always active.

OS: Windows XP SP2 :(

Possibly relevant other software: NOD32

Updated flash, current about:plugins info:
File name: npswf32.dll
Shockwave Flash 10.0 r12

Let me know if theres any more information I can provide.

Cheers,
James McGill

Are there any updates or news on this issue.
I love Chrome and really want to use it exclusivly in my day-to-day activities, but now I´m temporarily forced back to FF for my video-viewing online.

Any news/updates would be much appreciated.
Re: When Google Chrome runs, I see 100% CPU usage! Google Chrome Guide 11/17/08 4:16 PM
Hi all -- I wonder, do you have the latest Flash version? I've noticed significant improvements in performance since upgrading my Flash version to 10.  Let us know if that helps at all.

I've included a link to upgrade flash below.
Re: When Google Chrome runs, I see 100% CPU usage! dotnettech 12/22/08 2:42 PM
Disable the "Enable phishing and malware protection" option, which is found under the Security section of the "Under the Hood" tab. This solved the problem completely, and Chrome is now very light on CPU and Disk usage. However this raise a security risk and I'm not sure if this the right way of solving this. For me it was happening for most of the sites like cnn, bbc etc. I have xp sp2, chrome version 1.0.154.36 and flash 10,0,12,36.
Is there a issue in this module of phishing and malware protection?
Let me know if any more info is required

Re: When Google Chrome runs, I see 100% CPU usage! emailnike 1/25/09 8:11 PM
Well, I was still having this problem with chrome.exe taking about 72% of my cpu power. I came across this article but don't really want to disable the option. I also tried upgrading the shockwave flash and have the most latest one but to no effect. Did you know of any other way to solve this? This gives my problems even with youtube for example or any site with videos on it! Also, killing the chrome.exe which is taking the most cpu says the flash version crashes, which kinda makes me believe their still something on those lines!
Re: When Google Chrome runs, I see 100% CPU usage! emailnike 1/25/09 8:13 PM
Funny thing happened, I just tried to click on the "upgrade your version of flash" link and as soon as the site opened up my cpu went outta the roof!
Re: When Google Chrome runs, I see 100% CPU usage! Gobbledegook 1/26/09 1:37 AM
I don't have any problem with youtube videos anymore. Or for that matter Flash at all.

Thank you Google.
Re: When Google Chrome runs, I see 100% CPU usage! akhil1981 1/31/09 6:32 AM
i am using version 1.0.154.46 fully updated

still i have problem!!!!!!!!!!!!!!!!!!!!!!!!
why chrome use so much of processor????
Re: When Google Chrome runs, I see 100% CPU usage! Jeral P 2/16/09 2:05 PM
I've been having this problem for 3 months.  I'm now on 1.0.154.48, and I still have the problem.  Luckily I have a dual processor machine or I would have ditched Chrome long ago, but it still uses too much power and generates too much heat when one processor is running at 100%.

I've made sure my Flash is up to date.  I've disabled the malware & phishing option, reluctantly.  It still continues.  I notice that I can close every single tab, until Chrome is no longer visible in my Windows XP tool bar, but there is still a Chrome task running the background at 100%.  I have to kill that process in order to get my processor back.

Now, I've figured out something interesting.  If I start Chrome, the processor usage will go to zero.  These is even after it opens 2 or 3 different windows with multiple tabs each.  So it can load web pages without locking up the processor.  If the page that shows is something simple, like search results from google.com, I can even hit refresh and the processor will stay idle.  But as soon as I start interacting, such as changing to a different tab, it immediately goes to 100%.  Come on, Google, is that enough to figure this out?  Let me know if you want more details.
Re: When Google Chrome runs, I see 100% CPU usage! John Brett 2/18/09 5:40 AM
I've also noticed that it seems to be rapid interaction with Chrome that causes the 100% CPU usage to kick in. Opening two windows then immediately trying to spin off more tabs from the pages being displayed before they've completed loading and I have a pretty good chance of it happening. Having said that, if I leave a page viewing Yahoo! Mail, then it'll happen eventually. It is not restricted to one core, however - I have a 4 core machine and I've had Chrome using 25%, 50% and 98% of my CPU at various times. I really hate that Chrome is so good as a browser in every other respect, because I'd have uninstalled it long ago otherwise.
Re: When Google Chrome runs, I see 100% CPU usage! Tuzz 2/24/09 7:05 AM
I'm on version 2.0.164.0 using Vista Enterprise on an hp tc4400 with 3 gig RAM and I am still seeing the high CPU, Disk access and constant fan running that I saw with previous version.
Re: When Google Chrome runs, I see 100% CPU usage! Jeral P 3/2/09 1:43 PM
I solved the problem on my machine.  Cleared the cache, and things are fine.  I was even able to turn back on the options for Phishing and malware protection and DNS pre-fetching.

Specifically, I went to Wrench --> Clear Browsing Data.  I clicked the first 3: browsing history, download history, and empty the cache.  The first time I tried (when CPU usage was at 100%) I let it run for 12 hours and it never finished.  But I rebooted and started Chrome.  Then I ran this BEFORE telling it to restore my previous tabs, and it worked fine.
Re: When Google Chrome runs, I see 100% CPU usage! slowchrome 4/14/09 10:45 PM
I'm on 2.0.172.5 on a Win XP SP3 box with 2 gigs of memory and an AMD 3200XP+ processor.  After some period of time in Chrome, the Chrome process itself starts eating up exhorbitant amounts of CPU power 60-100% all the time regardless of what its doing.  I tried deleteing the browsing/download history and emptying the cache as well as turning off the options for Phishing and DNS Pre-Fetching, nothing worked.  I also tried turning off my Firewall (Sunbelt), Virus Scanner (AVG), and Spybot... No luck.

I've had this problem for several months now, but I didn't have this problem when I first installed it (when it was first released).  It used to be that individual tabs would start eating up CPU, typically associated with trying to run Flash, now the main Chrome process starts eating up CPU time, and does so very easily.

Some one pretty please help me out....
Re: When Google Chrome runs, I see 100% CPU usage! Crimm 4/16/09 1:50 PM
I'm having the same issue as slowchrome on multiple PC's over the past couple of weeks.

Same setup as well - XP SP3 one a Quad Core.

I believe it has to do with Java though.  I didn't experience issues until I installed the Java component that Sun isn't supporting ... :(
Re: When Google Chrome runs, I see 100% CPU usage! Gobbledegook 4/16/09 2:22 PM
Yeah. Started to have the same issues.

I'm running XP, Vista and Windows 7, all of them 64 bit, and Chrome crashes VERY frequently. So until Google comes out with a 64 bit version of chrome, I've EXTREMELY regretfully ditched Chrome.

Firefox and Speed dial have restored some semblance of order into my browsing life.

I miss you Chrome :(
Re: When Google Chrome runs, I see 100% CPU usage! Crimm 4/16/09 2:24 PM
I'm not having the crashing issues on my 2 Vista 64 bits.

Just the performance robbing.
Re: When Google Chrome runs, I see 100% CPU usage! Gobbledegook 4/16/09 2:31 PM
Yeah, it's more of a Windows 7 issue. And no way am I ditching Windows 7. It's become central to my computer usage. Just too good to stop using.
Re: When Google Chrome runs, I see 100% CPU usage! John Brett 4/17/09 12:49 AM
I've recently switched from XP to Windows Server 2008 x64. Despite having a lot of problems with Chrome on XP using 100% CPU, I brought it across. It has been absolutely great under Server 2008, never taking an inappropriate amount of CPU, so it certainly does work well on a 64 bit OS. Having said that, today I had my first Chrome issue - shockwave flash player stopped responding.
Re: When Google Chrome runs, I see 100% CPU usage! misanthropic777 4/17/09 11:03 PM
I'm still having this - 1.0.154.53 on windows xp pro sp3
1.2ghz pentium m processor
1.5G ram
I just reinstalled the OS, and am not running anything else in the foreground.  (Comodo, avast and jungledisk are in the background, but I never see them rising up on the process list.)  What I DO see is chrome opening up multiple processes and even when it appears that all tabs have downloaded everything and are done the processes are still burning 30-40% cpu.  Heck with only a single tab open I'll see 2-3 chrome processes eating my cpu.  Frankly I'm about ready to give up.
Re: When Google Chrome runs, I see 100% CPU usage! slowchrome 4/20/09 7:23 PM
Crimm, I tried uninstalling all my java updates which was all I could find Java related in the installed software list.  Didn't help.  Tried installing Java 6 Update 13 (latest one on their website)... Didn't help.  Do you have a recommendation as to how to fix it if this is a Java issue?
Re: When Google Chrome runs, I see 100% CPU usage! Crimm 4/21/09 9:01 AM
I gave up mostly... :(

I ended up playing with Ubuntu 9.04 on my main computer and Chrome doesn't work for it, so I'm using FF 3.  Unfortunately I love Chrome so much that I'm using Chrome themes and addons to make it look like Chrome. :)

I'm going to be redesigning my Quad Core Vista 64bit today... If I can figure out anything, I'll let you know.  Also: I'm not 100% sure it's Java, because I'm seeing the same issues on youtube and other flash related sites.  For example sometimes watching a full screen video can cause Chrome to eat 100% CPU... ? As far as the Java issues, last I saw Java said that they don't fully support Chrome (Good luck they say :P), but sometimes it causes issues and performance issues as well.  For example sometimes the Java on facebook, just flat out doesn't work... Other times it does. That's where I was going with that.

/shrug

I'm at a loss... I wish I could be of some help.
Re: When Google Chrome runs, I see 100% CPU usage! slowchrome 4/21/09 10:01 PM
Well, after playing around with it some more, I noticed something interesting.  I now strongly suspect the problem is related to Flash.  I believe I'm running Adobe Flash 9.  I've had a number of website complain I wasn't running Flash 10. I tried installing Flash 10 by downloading and running the program from Adobe's website, and ran into two problems:

1) For some reason, Chrome doesn't like to download files.  I've noticed this before, and it seems to get progressively worst.  It used to bring up a little tab at the bottom of the screen, then it would do it but take longer and longer for the tab to pop up, now it doesn't, it doesn't appear to do be doing anything at all in fact.  I was able to download it by right clicking and downloading on link.  This may be a completely unrelated problem.

2) Once I did download it, and install it, it installed it installed as an Opera plugin, it wasn't installed at all in Chrome.  I copied the plugins directory from Opera to Chrome to get around this.

Once I did that the behavior changed radically.  For a while, my main Chrome browser (not the tabs) started grabbing and returning massive amounts of memory for no real obvious reason (several hundreds of megabytes) but the Chrome process did not monopolize the CPU.  Then the behavior changed back, and the browser used very little memory but started monopolizing the CPU.  So I think something is going wrong with Flash.

I'm using the latest Flash on Adobe's website, but I'm wondering if there is a later version somewhere.  This is annoying...  Maybe I need to play with Opera again.
Re: When Google Chrome runs, I see 100% CPU usage! Lonndoggie 4/23/09 3:46 PM
Help, this is even worse for me.  When I start chrome, it consumes all the cpu cycles of one of my (old) hyperthreaded processors.  If I close chrome, there is still a task running, still consuming that whole processor.

I've tried turning off the filters, clearing cache (which never finishes, btw).  I like chrome, but I can't live with a CPU hog that leaves behind a CPU hog zombie process.
Re: When Google Chrome runs, I see 100% CPU usage! AM_ 4/24/09 8:27 AM
CPU usage goes to 99% as soon as I visit any website (I've tried GMail, GReader, Facebook).
1. only 1 tab open. the website still loads but very slowly and ofcourse the computer response is delayed to mouse movement etc.
2. the CPU usage for one of the "chrome" processes hovers around 50-99 (almost always above the 50% mark). Sometimes another chrome process will also claim 20-30% of the CPU
3. I am running Chrome 1.0.154.59. I have uninstalled and reinstalled a couple of times already. I have uninstalled all google components including gears etc and reinstalled. I have been trying this for a couple of days
4. Abode Flash 10.0.22.87. This also I have uninstalled and reinstalled
5. Ran virus scans and malware scans
6. Used Chrome with all firewalls and anti-virus programs off

Alternate:
Internet Explorer 7 (7.0.5730.11) has no such problems. Takes a few (single digit CPU) when first loading and then works normally for all websites and all tabs etc.

System
Windows XP 5.1.2600 SP 3 Build 2600
RAM 1GB
Processor Intel Pentium 2.00GhZ
Re: When Google Chrome runs, I see 100% CPU usage! dubc 4/25/09 6:55 PM
I started having the same exact problem as AM_ randomly. Just started not working. It was fine, and now it isn't. No software updates etc.
Weird.....it's basically unusable with ANY website, even ones without flash.
Re: When Google Chrome runs, I see 100% CPU usage! Gobbledegook 4/25/09 7:31 PM
dude. forget it. Chrome is history. until google gets its act together its going to be left far behind in the browser market. at this point i guess they've only got 2 or 3 programmers workign on it, not even full time.

google devs; here's whats broken about ur browser:

1. lacking in flash compatibility
2. lackign in browser stability (guaranteed browswer crash every 10 mintues)
3. poor rendering of your OWN gmail. FF 3.0.9 does  an amazing job scrolling thru large emails / large number of displayed emails, whereas your browser jerks thru.
4. lack of attention to the aforementioned. this is clearly visible by your focus on useless extras like 3D browsers. Your app doesn't have wheels to run on and you're upgrading the engine.

Inspired.

I'm normally very supportive of Google, but wrote all that in a bout of frustration.
Re: When Google Chrome runs, I see 100% CPU usage! nakro 4/25/09 7:31 PM
try the following :

wrench->clear browsing data (wrench is that rightmost icon in the address bar)
and make sure
clear history is checked
and 
empty the cache is checked
and press clear browsing data 

while it is true that there are issues with flash player and chrome (and they rarely happen, especially if you update the player)

i am not aware of any other issues related to speed and chrome.....

happy chroming...

as in OS, system hardware


and i've tried chrome with a clean OS install and obviosly clean chrome install. no juice.

true.

can I ask why you're not using win 7 rc ?

ure missing out mate.
Re: When Google Chrome runs, I see 100% CPU usage! Lonndoggie 4/25/09 9:59 PM
I think i've resolved it.  We'll see if it stays solved.

Clearing browsing data wasn't working for me--it would hang, and never complete.

So I went and found the cache directory (C:\Documents and Settings\<me>\Local Settings\Application Data\Google\Chrome\User Data) and nuked everything except the folders and the stuff in Google Gears.

Started chrome, and so far, CPU is idling.

I'll post if it redlines again.
Re: When Google Chrome runs, I see 100% CPU usage! slowchrome 4/29/09 8:52 PM
Lonndoggie, I think you solved my problem.  I didn't pay too much attention to what was in there but there was a 15 gigabyte file called History.  Seems a bit excessive.  I've been using Chrome now for about 10 minutes and my idle CPU according to the Chrome Task Manager is about 0%, ordinarily it'd be 99% by now.  Kind of makes sense now why this got progressively worse.  I wonder if I will just have to kill off the History file periodically.
Re: When Google Chrome runs, I see 100% CPU usage! Shawn (Googler) 5/28/09 5:04 PM
Thanks for sharing all the additional information guys.

When you see abnormal CPU usage, can you go to Google Chrome's task manager (shift+esc) and see if there are certain processes that are consuming a lot of your CPU? If there's a pattern or common culprit, it'd be easier to diagnose.

Thanks!
Shawn
Re: When Google Chrome runs, I see 100% CPU usage! Gobbledegook 5/28/09 5:11 PM
Shawn, do you notice that on Chrome, scrolling 100 messages in gmail is really slow? On Firefox, it's snappy.
Re: When Google Chrome runs, I see 100% CPU usage! nakro 5/28/09 5:29 PM
gobble sadly you are right, but this is a known issue and is rooted deep inside how chrome and gmail work, hopefully it will be better in the future

Re: When Google Chrome runs, I see 100% CPU usage! hawkfarm 5/29/09 12:52 PM
I'm using Chrome 2.0.172.30 - Win XP 4GB RAM . I have always had high CPU usage in chrome since early in version 1. Chrome task manager always show Shockwave as the culprit, regardless of the version of Shockwave. Once I kill the Shockwave thread it immediately starts to behave itself. Unfortunately some ad in some new page always restarts it. I have just about stopped using Chrome. Shame because I like the browser!
Re: When Google Chrome runs, I see 100% CPU usage! MrBlack 6/1/09 6:12 AM
FIXED!!! I was having the CPU prob on my PC, cleared the cache and (this may sound silly) hoovered out my entire CPU tower, a year's worth of dust can't of been helping. Anyway, in general, clear the cache and get the Dyson out!
Re: When Google Chrome runs, I see 100% CPU usage! Lonndoggie 6/1/09 11:04 AM
A late follow-up to my post about manually clearing cache having solved my problems.  It did solve the problems with high CPU, but Chrome would crash fairly frequently still.

However, since I upgraded to...ah...whatever the latest rev is, the crash problem is gone.  The only problem I'm having with it now is that it won't remember my igoogle login!  Kinda silly, that.

Shawn, thanks for the tip on Google's task manager--I wasn't aware of the existence of that.

Re: When Google Chrome runs, I see 100% CPU usage! blaak 6/13/09 3:01 AM
Same problem (CPU usage Chrome nearly 100% after a short time on internet) started recently on my computer: Win XP SP3, Chrome 2.0.172.31, AMD Sempron processor 1.8 Ghz.

Had no problems with Chrome before...
Re: When Google Chrome runs, I see 100% CPU usage! seanmullins 6/19/09 6:01 AM
Hi, I'm seeing this too -
seems to happen when I leave some tabs open - usually have gmail open -
one of the reasons I tried chrome was gmail was slow in FF!

Chrome 2.0.172.31
Windows XP SP3

Now that I see the post about the task manager I will keep an eye on it and see if I can add anything.
Re: When Google Chrome runs, I see 100% CPU usage! SJoshi 6/20/09 3:51 PM
Hi all,
Chrome (I think its Chrome, because I've checked for viruses and spyware and the like, and I haven't made any changes to my computer habits in months) seems to be guzzling CPU power. Not the 100% that there are complaints about, but just having it open is slightly (but definitely noticeably) hindering the process of doing anything else on my computer. I've just noticed this problem within the past week or so, so perhaps there was an update recently I know nothing about?
Chrome 2.0.172.31
Windows XP SP3
2gigs of ram

I'll also keep an eye out in the Chrome task manager...
Re: When Google Chrome runs, I see 100% CPU usage! Atchoum1979 6/23/09 7:22 AM
Hi Everyone,

Same issue here, for the past 3-4 weeks, my computer has been very slow. I realised it was Chrome making my CPU go to 100% for no obvious reasons. Even with just one tab open, it goes all over the place. I've got version 2.0.172.33
I really hope they can solve this quick. I have to go back to Firefox in the meantime as I need my CPU, but hope Google will sort this mess up very quick. When is the next big release coming out? Hope they include easy add-ons like Firefox as well.
Re: When Google Chrome runs, I see 100% CPU usage! xu20cn 7/2/09 12:22 AM
Hi all,

I have the same problem like "Atchoum1979", with the newest 2.0.172.33, and sometimes meet "cpu100%"
Re: When Google Chrome runs, I see 100% CPU usage! spetnik 7/5/09 5:36 AM
Also with 2.0.172.33. Crazy CPU usage.
Re: When Google Chrome runs, I see 100% CPU usage! atingoldy 7/10/09 5:36 PM
Hi All,

I found same issue but differently. I opened 7-8 chrome windows(no tabbed browsing) and browsed different sites, watched few flash videos. After few houres I realised that my laptop is heated up and fan is making lot of noise. I checked task manager, chrome was taking 50% of CPU (laptop with Core 2 Duo 2.5 GHz CPU, 3GB RAM, Chrome version 2.0.172.33, Vista Home Premium SP2). I started closing all the instances of chome and kept checking CPU. I closed all the chrome instances and still found one chrome instance is still running in task manager with 50% CPU. I killed that process and my laptop started working normally.

Hope they solve it quickly.
Re: When Google Chrome runs, I see 100% CPU usage! ioresult 7/14/09 2:41 PM
I have version 2.0.172.33 and the cpu spikes at 100% for 10 seconds out of every 60 seconds or so. No need to load any page at all.
Re: When Google Chrome runs, I see 100% CPU usage! Shawn (Googler) 7/20/09 3:20 PM
Guys, as mentioned previously, can you guys look at Google Chrome's task manager (shift+esc) and let us know if there are certain tabs that are causing this? Google Chrome's task manager will give much more insight into what tab is causing it as opposed to the general Windows task manager.
Re: When Google Chrome runs, I see 100% CPU usage! markpb 7/21/09 11:53 AM
Shockwave Flash seems to be the killer for me - it takes up so much CPU it can't play videos from YouTube properly. Even when I shut down the YT tab, the Flash process stays at 50% for a few seconds or minutes afterwards.

I'm on 0.3.154.6 on WinXP SP2 with the anti-phishing functionality turned off.
Re: When Google Chrome runs, I see 100% CPU usage! nonplusplus 8/6/09 12:52 PM
I'm having this problem as well.  To echo what someone else said: "I've also noticed that it seems to be rapid interaction with Chrome that causes the 100% CPU usage to kick in. Opening two windows then immediately trying to spin off more tabs from the pages being displayed before they've completed loading and I have a pretty good chance of it happening."

I just noticed this happening.  I opened up a new window and did a google search.  Then I ctrl-clicked three of the images that displayed so that I could see them in separate tabs of image search.  In the chrome task manager I could see that the tab was maxing out one of my four cores - 25%.  It just stayed there.  None of the three tabs it was loading did anything except spin.  I can reproduce this any time I like.  I just did it half a dozen times.  

OK, got it.  It was one of the tabs in particular that did it...

Any time I go to this address the tab that I use will max out my core at 25% and freeze.

All of the other tabs were fine.  And if I just got straight to the site...

... then that's also completely fine.

I'm using Chrome 2.0.172.37.  Win XP service pack 2.
Re: When Google Chrome runs, I see 100% CPU usage! timscarfe 8/15/09 9:14 AM
Can I post my 2 cents here too.

I am having some issues with browsing too and they present themselves either when interacting with Flash content, or downloading files or both. These two workflows.

First of all I am not going to mention CPU usage because its irrelevant. I took a look at the task manager and it never really shows above 11% or so for me. I have a quad core machine too which would skew the numbers anyway.

The relevant thing here is that the UI thread in Chrome is clearly and obviously getting blocked -- all the time when these two workflows are present. Often when browsing with multiple tabs (always one with flash content) the browser can hang for extended periods. Often when you are commenting on facebook or something which is excrutiatingly annoying.

Flash first. On a typical video it is clear that that the UI thread is getting blocked because while the video is playing if you mouse the hyperlinks to other videos, the cursor intermittently changes to a hand when the thread stops getting blocked. While the thread is blocked you can't scroll either. This loss of control is absolutely infuriating. If you go full screen during a loss moment it's also infuriating.

I am running Windows 7 RTM now (it was just as bad with Vista) and have latest beta Chrome. I have tried the latest nightly too. Have latest Java update, and latest Flash (10.0 r22). I have cleared all my cache etc (had to let it process that one for best part of 30 minutes). I also cleared the phishing checkbox which seemed to have some tiny impact.

The next comment I would like to raise is that the responsiveness of Chrome can be greatly affected by files that are downloading. Actually if the download is running slowly the UI thread can get severely blocked and any update can be sloooooow. Seemingly the UI update is blocking on some server download chunk request. I can't believe nobody else pointed this out before now -- I have googled it. I thought it must be a problem with my machine specifically so I tried bypassing my router, and also upgrading my network drivers (I have a Broadcom Netlink Gigabit). I must admit though I have seen similar download-related slowdowns in FF on the same box. Although downloads in a command shell using wget.exe or similar don't imact system performance. What's more annoying is that when Chrome hangs, it can cause the shell to become really sluggish too! I have no idea how this is even possible but it happens.

As much as I detest Internet Explorer -- it doesn't have the Flash slowdowns. There is the occasional second of unresponsiveness but it's at an acceptable level. I just checked FF and it doesn't have the Flash issue either although I wouldn't rule out the download slowdown as I recall having that in FF too.

Cheers,

Re: When Google Chrome runs, I see 100% CPU usage! timscarfe 8/15/09 9:26 AM
Sorry I have to retract my statement, I've just been playing with FF and it's just as bad as Chrome. So it's gotta be a Flash issue or a "my machine" issue. Another comment is that it seems to get cumulatively worse over time i.e. play the same 8 minute video a few times.
Re: When Google Chrome runs, I see 100% CPU usage! Gobbledegook 8/15/09 9:30 AM
I used to have this problem, the shockwave flash plugin consuming an inordinate amount of CPU, but somewhere down the line the issue resolved itself. So I'm happier now.

Now if only we could get smooth gmail scrolling and a more effective Adblock Plus for Chrome extensions, Chrome would be perfecto.
Re: When Google Chrome runs, I see 100% CPU usage! timscarfe 8/15/09 11:27 AM
OK I made a screencast to demonstrate some of these issues -- http://www.youtube.com/watch?v=ZU26iQAEMfI

It was not relevant to show the Chrome task manager as the CPU never got above about 2-4% on anything (quad core machine).

My basic specs are quad core 3Ghz, 8GB ram and running a very high screen resolution like 2500ish x 1900ish and also dual monitors

@timscarfe
Yes you are right.
Something is going wrong.

Chrome uses 100% CPU usage!
Chrome version is 3.0.197.11
Re: When Google Chrome runs, I see 100% CPU usage! suavi 8/18/09 2:19 AM
I updated it into latest 4.0.201.1 version.
But problem still is going on.
Re: When Google Chrome runs, I see 100% CPU usage! Shawn (Googler) 8/20/09 10:45 AM
@timscarfe: Thanks for providing such detail. I tried to reproduce the issue you describe using Google Chrome version 4.0.202.0 (dev build) and couldn't reproduce. When visiting the same video, I don't observe any blocking of hyperlinks or scroll bar. When I open up the Google Chrome task manager (shift+esc), the YouTube tab doesn't use up any CPU and the Flash plugin uses up anywhere from 5-10. However, if I drag the scroll bar up and down, it'll cause the YouTube tab to use up CPU of 15, but no blocking. 

Are you comfortable installing the dev build and testing it out?
Re: When Google Chrome runs, I see 100% CPU usage! twhaley02 8/20/09 3:53 PM
@Shawn:  Here in our IT shop we're seeing this across Chrome and Firefox, so I don't think it's Chrome's problem.  It started a couple days ago.  In Chrome it makes my dual core crank up the CPU to 100% on one of the cores, and if I kill the process that is running away then the shockwave plugin is the thread that dies.  It only occurs when I leave a page with flash on it open for about 30 minutes.  I don't have to be doing anything during this time, just open something with flash and let it be and eventually it'll manifest itself.
Re: When Google Chrome runs, I see 100% CPU usage! suavi 8/20/09 4:18 PM
@twhaley02
Yes, absolutely this problem was started a couple days ago.
I tried this situation in Ubuntu without update my chrome. I only update my Adobe Flash Player. It starts to use it again high. :(

After that, I uninstalled Chrome and Adobe Flash Player from my Vista  and install them again with latest versions.
Now there isn't any problem I can see. But I will try your description. I will write results here.
 
When I checked Adobe Flash Player Bugs site, I saw some people who opened new issues about this high CPU usage problem. Very interesting issue.
Even I think that maybe there is a problem with Windows Security.

I don't sure what causes it but I am sure it started a couple days ago. Not so long time ago.
Re: When Google Chrome runs, I see 100% CPU usage! suavi 8/20/09 4:20 PM
Oh I forgot to add which versions now I am using:
Chrome 4.0.202.0
Adobe Flash Player version 10.0.32.18
Re: When Google Chrome runs, I see 100% CPU usage! kfir 8/21/09 8:33 AM
I'm experiencing the same problem with chrome latest RTM 2.0.172.39 with shockwave 10.0.32.18
flash adds are killing my cpu until chrome suggest to kill shockwave plugin

I use windows xp sp3
Re: When Google Chrome runs, I see 100% CPU usage! timscarfe 8/22/09 6:31 PM
Hi Shawn -- no probs would love to work with you guys on this one. My mail address is tim [at--] dotnetsolutions.co.uk

I had already tried the latest nightly of Chromium and that exhibited the same problem.

It's really got me stumped to be honest. And to make it worse -- the problem is intermittent. Every now and then the problem is completely absent. I thought it might be my internet connection or router but I have other PCs on the network which perform fine using Chrome and playing videos etc. I have a feeling that the problem has nothing to do with Chrome whatsoever but it's very difficult to track down.

I can do a (sysinternals) process monitor trace and send that to you guys if it would help while recording the repro.
Re: When Google Chrome runs, I see 100% CPU usage! Shawn (Googler) 8/24/09 6:08 PM
Very interesting indeed guys. Thanks for trying the latest nightly tims. 

Since this seems to be exhibited in both FF and Google Chrome, let's see if altering Flash behavior itself helps. This is taken from the Adobe forums referenced below. Can you guys test out changing the Security settings on your Flash files - Flash10c.ocx and FlashUtil10c.exe? Try setting it to Everyone, Allow Full Control.

For XP and Vista, the location should be something like this:
C:\Windows\system32\Macromed\Flash
Re: When Google Chrome runs, I see 100% CPU usage! walit 8/24/09 10:42 PM
First I thought this was a Windows XP problem. Then one day I saw Chrome consuming 99% of CPU. Decided to check Chrome's Forums. I think it is XP problem, because it appeared BEFORE I installed Chrome for the first time on this computer.
 Any thoughts on fixing this Windows XP problem? I could not find any plausible solution anywhere... Except reinstalling Win, of course... (which would be too time consuming for me).
Re: When Google Chrome runs, I see 100% CPU usage! timscarfe 8/26/09 12:51 PM
Did a trace on the system while it was blocking on a flash control

Seems to be wasting a LOT of time calling MallocExtension::VerifyAllMemory -- that call seems to take forever because it recursively calls into shell32 a million times (check it out)
http://www.developer-x.com/dropbox/chrome/verify_allmemory.png

Seem to be wasting the next biggest proportion of time calling into fltmgr.sys which is something to do with the file system -- this might be an effect of the next thing which is that it seems to be hitting the cache HARD on the file system
http://www.developer-x.com/dropbox/chrome/fltmgr.png

See we are hitting the cache really hard for some reason -- 10,000 ish events?
http://www.developer-x.com/dropbox/chrome/filesystem.png

Will try your suggestion re: permissions

Re: When Google Chrome runs, I see 100% CPU usage! timscarfe 8/26/09 3:29 PM
Some other comments RE: memory -- my system here has 8GM ram which may be unusual. Also it's 64bit and chrome seems to be a 32bit image which explains the wow64 virtualization

I set an ACL (Everyone--Full Control) on C:\Windows\SysWOW64\Macromed\Flash -- and seems no effect.

Also I got a really good repro for you guys now -- check this page

http://www.alldj.org/index.php?name=News&op=Article&sid=28408

When the flash control loads and starts playing Chrome will consistently freeze up for about 10 seconds -- this was the basis of my trace earlier. Hurry and check it before it changes. This one is a dead cert repro every time
Re: When Google Chrome runs, I see 100% CPU usage! timscarfe 8/26/09 3:32 PM
Defo a Flash issue and not a Chrome issue because that link freezes up Firefox even worse than Chrome! Internet Explorer 8 though is completley immune to these freeze ups. WIERD!
Re: When Google Chrome runs, I see 100% CPU usage! timscarfe 8/26/09 4:53 PM
OK -- we have a development

I was examining the traces and first saw a lot of registry activity related to my audio card (on board realtek HD thing). Tried updating driver and no effect, although was an old driver.

I decided to do a fresh trace -- and this time Chrome went berserk and blocked harder than it ever had before. And I captured it all on trace. NICE

http://www.developer-x.com/dropbox/chrome/another_filesummary.png

Again look at the amount of time wasted -- chrome is constantly wanting to write into the cache file -- thousands of writes (and to a much lesser extent, history and cookies). Why is this?

So I had a brainwave to try loading the same page in "incognito" mode because then in theory nothing is getting cached etc. Guess what -- IT WORKED PERFECTLY, NOT A SINGLE HANG UP.

So what is the deal here Googlers?
Re: When Google Chrome runs, I see 100% CPU usage! timscarfe 8/26/09 5:00 PM
Another thought is that when I empty my cache -- it takes like 30 minutes??? As a guess -- maybe I have "too much" stuff in my cache because I would guess it's not supposed to take 30 minutes to clear the cache on most peoples machines.
Re: When Google Chrome runs, I see 100% CPU usage! timscarfe 8/26/09 5:01 PM
Been playing some more -- the problem is 100% fixed in "incognito" mode

Re: When Google Chrome runs, I see 100% CPU usage! timscarfe 8/26/09 6:29 PM
It seems this was the cause of all my Chrome problems.

In incognito:

*File downloads no longer block Chrome UI
*Chrome is generally SO MUCH FASTER I can't even believe it -- i.e. even Google Maps application runs 5x faster. The performance improvement is incredible

So the 64 million dollar question -- why on earth are all versions of Chrome on *this* PC hammering the cache and other stores (especially when Flash content is present, and while downloading files).
Re: When Google Chrome runs, I see 100% CPU usage! suavi 8/26/09 6:56 PM
Wow!
What an effort is this @timscarfe!
Congratulations!
Re: When Google Chrome runs, I see 100% CPU usage! timscarfe 8/29/09 8:39 AM
bump -- Shawn have you seen this yet? Would appreciate some insight from the team on this one.

The problem always happens on one of my machines here regardless of the version of Chrome -- and apparently even the operating system. It still happened on this machine back when I had Vista installed (before Windows 7). Now with Windows 7 I have updated all of the drivers but no effect.

For some reason Chrome wants to hammer my Cache -- causing significant UI blocking when downloading files and displaying some Flash content.

Some more information:

Windows 7 Ultimate RTM x64
Duad Core2 Q9650 @ 3Ghz
8GM Ram
Foxconn "Blackops" Motherboard
->Onboard Broadcom Netlink Gigabit NICs
->Onboard Realtek HD Audio
NVidia GeForce GTX 280
2*SSDs in Raid0 configuration using the mobo onboard RAID controller
2560*1600 screen resolution

If I were you guys -- I would set up a test build that logs the stack traces etc when caching so I can run it this end for you
Re: When Google Chrome runs, I see 100% CPU usage! timscarfe 9/2/09 7:13 AM
bump again?!! no comments on this? I still have to visit everywhere in incognito mode to prevent my system from hanging. All the disk access even causes other programs and the shell to hang!!!
Re: When Google Chrome runs, I see 100% CPU usage! Neotangerine 9/2/09 11:15 AM
This problem started to occur for me after the Gmail crash on 9/01/2009. It affects Chrome and other browsers(I also tested Firefox as well) as well. I get a constant CPU usage of 60%+ while I am logged into Gmail. As soon as I log out and I am at the log in screen the CPU goes back to normal. I've tried clearing browser data for the last week thinking it might of been something the Gmail crash might of caused, but it did not help. I also tried using incognito mode as suggested above with no difference.

More Info:
Chrome version : 2.0.172.43
Windows XP 32bit SP3
(Dell D830)
Intel Core 2 Duo T7500 2.2 Ghz
2Gb RAM
No unusual software.

Thanks for the help.
Re: When Google Chrome runs, I see 100% CPU usage! Shawn (Googler) 9/2/09 3:43 PM
Thanks for the helpful information and for troubleshooting this with us Tim. Still looking into this and have moved your conversation to the specific Issue Tracker that references your problem. Thanks again for your patience!
Re: When Google Chrome runs, I see 100% CPU usage! timscarfe 9/2/09 8:11 PM
Shawn -- we figured out the problem.

Chrome likes to cache all binary data coming down (including live Flash video) in an incredibly chatty manner to the file system. I have solid state hard drives in RAID0 and it turns out that SSDs are incredibly slow at doing lots of small writes. This was the cause of the problem.

My solution was to link the Chrome and Temp folders on my system to duplicates on another (non-SSD) drive using the dlink.exe tool in the Windows Resource Kit.

This is clearly a problem going forwards because SSDs are getting more and more prevalent.

Thanks again for all the help.

Re: When Google Chrome runs, I see 100% CPU usage! R Cavalcanti 9/15/09 8:07 AM
The chrome.exe keeps using the most of CPU when I'm logged in Gmail, but only when I'm behind a proxy server.

Chrome version: 3.0.195.21

I'm also running Gmail Labs offline feature.
Re: When Google Chrome runs, I see 100% CPU usage! xspeedballx 9/19/09 3:31 PM
I have cleared my cache, tried running in privacy mode, uninstalled and reinstalled both chrome and flash.  However consistently after a few minutes I found cpu usage shoots up "50%", or one of my cpu's.  If I close chrome this persists.  I ran the chrome task manager and it will tell me that the "Browser" is at 50%, and whatever tab I am at is from 0-10% depending on what I am doing.  Any kind of searching or usage of the browser will cause the problem within a few minutes.

I am running Chrome version 3.0.195.21 on Windows 7 RC(build 7100).  This issue has seemingly started "recently" meaning about the last 3 or 4 weeks, and was fine prior to that.
Re: When Google Chrome runs, I see 100% CPU usage! James Ponds 9/24/09 12:15 PM

Re: When Google Chrome runs, I see 100% CPU usage! osman 9/25/09 9:04 AM
Hi,

This problem started with me today, up to today i had no problem using Chrome and it was my default browser. Today i realized that Chrome uses about 80% of CPU. If open a page with no flash, like this page you're reading this, the Browser process (in the Chrome task manager) uses 40%-50% itself. If i also have Flash process running, it uses another 30%-40%.

Another problem is, when i exit Chrome, one chrome.exe process still remains with 40%-50% CPU usage. It doesn't matter how long i wait it doesn't stop.

Chrome version: 3.0.195.21, beta channel
OS: XP Professional SP3
on an HP 6910p laptop

Did anyone solve this issue yet?

Just now it came to me, did anyone try switching back to stable channel to solve this? I'l go through every solutions offered here and then try going to stable channel if i can't still solve it.

I've been using Chrome from day one, and never had any serious problems until today. I'll have to switch back to IE :(
Re: When Google Chrome runs, I see 100% CPU usage! osman 9/25/09 10:13 AM
i tried these:

A. deactivated "enable phishing and malware protection" option, didn't help.

B. cleared all kinds of cache/history using "clear browsing history" menu item. cleared about 800 MB data. didn't help.

C. uninstall chrome and flash and reinstall, and it worked for me...

1. exported my bookmarks
2. uninstalled chrome
3. made sure nothing left related with chrome in program files, local settings\applications data etc.
3. changed from beta channel to stable channel, using channel changer
4. uninstalled flash, with uninstaller from adobe
5. reinstalled chrome, stable channel
6. imported my bookmarks back (thanks to chrome, my bookmarks are all at the same place as before, same order etc...)
7. reinstalled flash (opened a page with flash and chrome prompted to install flash plugin)

now it looks better.

also now no chrome.exe process is left when i close chrome.
Re: When Google Chrome runs, I see 100% CPU usage! marchesi 9/29/09 4:14 AM
My observations with Chrome system overloading (mem/cpu), similar to many others in this thread:

when behind proxy (at work): XP/SP3/pentium D 2.67G/1G ram
- with gmail open: 100% of times, 40-100% cpu usage (one core mostly)
- with flash page running: 100% of times, 10%-25% cpu usage increase
(please see cpu usage at http://picasaweb.google.com.br/bruno.marchesi/Sift#5386843663421623618)

no proxy: (both XP and Seven, AMD Athlon dual core @ 2.4G/2G ram)
- it appears to not be any overloading

As a footnote, the cooler here at work is very noisy at higher duty cycles, so I can 'hear' when someone
is giving that punch on the system. This occurs allways when there is a gmail tab opened,
or when there is some hard fight going on with Matlab and other greedy applications. I feel that should not
be the case with gmail nor Chrome.

Didn't try osman tips yet, though.
Re: When Google Chrome runs, I see 100% CPU usage! marchesi 10/1/09 4:11 AM
Yep, today I've tried gmail at work with wifi (no proxy), and there was no burden to the system. From what I've seen here, the link between gmail  (and flash, by the way) overloading and proxy seems pretty much conclusive.
Re: When Google Chrome runs, I see 100% CPU usage! R Cavalcanti 10/1/09 6:21 AM
I’ve found how to avoid the issue: it happens when the proxy blocks gtalk chat. If you minimize gtalk’s frame, everything seems to be back to normal.
Re: When Google Chrome runs, I see 100% CPU usage! Neotangerine 10/1/09 10:56 AM
Following R Cavalcanti's suggestion, I can confirm that this does help, at least with my case. As soon as I collapse the Gmail chat my CPU usage goes back to normal. As soon as I expand the chat window the CPU instantly goes back up to 60%+. This only happens at my work place which is behind a proxy that blocks Gmail chat.
Re: When Google Chrome runs, I see 100% CPU usage! marchesi 10/2/09 3:45 AM
Same effect here: behind proxy, Gmail talk opened - 60%-90% cpu usage, Gmail talk collapsed - 10-15%.
But that's not all.
Open Chrome, than access Gmail account ~ 10% cpu usage.
Open another tab with some flash content, keep Gmail opened - 60-90% cpu.
Close tab with flash - 60%-80% cpu.
It looks like some interation between proxy-web/net protection software- flash/Gmail & Chrome.
I'd better listen to what Google experts have in mind... let's wait...
Re: When Google Chrome runs, I see 100% CPU usage! Geckex 10/14/09 2:49 AM
Hey - I'm on version 3.0.195.27 and see this intermittently - but frequent!

If I go to the Chrome task manager - none of my tabs are doing anything CPU wise - but the overall chrome is running at +90% of my CPU.
This is on a dual core Vista PC. I can close down all tabs and leave one last tab on the http://google.com - and Chrome continues hogging my full CPU indefinitely.

You boys need to fix this - I'm back to Firefox again - please post updates when you do thou - we love Chrome!!
Re: When Google Chrome runs, I see 100% CPU usage! tim.clymer 10/15/09 6:19 AM
I'm on 3.0.196.2 and I'm seeing this as well.  I'd echo the statements of others in that it appears to be gmail chat-related when chat is blocked by the workplace.  I'd definitely be interested in when this gets resolved.  Is Google tracking this issue, is it scheduled for a fix?
Re: When Google Chrome runs, I see 100% CPU usage! LazyAlex 10/15/09 1:44 PM

Re: When Google Chrome runs, I see 100% CPU usage! sunandajit 10/16/09 11:15 PM
I am using Dev channel 4.0.222.12 and the problem persists. Websites containing rich shockwave movie or youtube videos take upto 100% of CPU usage. Hope this is fixed ASAP in all three channels.
Re: When Google Chrome runs, I see 100% CPU usage! DS scorpion 10/23/09 1:40 PM
Heres what happened with my PC.

Idle temp = 45 deg Celsius, i ran chrome for 10 minutes then load temp = 61 deg Celsius, I closed Chrome then temp = 47 deg Celsius.

OK, this is what I found out. I am now using the latest version of Chrome. I like it's simplicity. It does not use a lot of RAM but it consumes a lot of CPU usage. I used some software that verifies all running processes at the background of a PC. And what I saw was that it is not just as simple as it looks. When you run Chrome, it run's multiple components which includes the Google Updater. I don't see anything wrong with what's happening but the fact remains, I believe the Chrome team should take a look on how much the background components consume CPU usage and MAYBE try to sort out what needs to get modified to perform on a much efficient manner. Please correct me if i am wrong.
Re: When Google Chrome runs, I see 100% CPU usage! Speedyfeetz 10/25/09 2:10 AM
Currently on version 3.0.195.27, still had the problem with the often noted additional symptom that closing Chrome still left one process that pegged CPU at near 100%

Lonndoggie's method got me on the right trail.

Basically, I shut down Chrome and then killed the one Chrome process that wouldn't go away.

Then, In the folder
(C:\Documents and Settings\<me>\Local Settings\Application Data\Google\Chrome\User Data\Default), I didn't delete anything - I only the renamed the index file for the current month - ("History Index 2009-10" to "History Index 2009-10.evil"). I left the "journal" file and the big History file itself.

Then, I restarted chrome and let it rebuild the index (which took a couple minutes) by selecting "View Full History" from the New Tab window. CPU time was pegged until it actually showed the history, then it went down to normal.

It's been smooth since then, I've done flash pages (which have never really optimal in Chrome) and pages with lots of javascript and server side feeds, refreshing large content.. All seems well. Apparently there is an issue with history indexing. At least that's what I think today.

Good luck.

Most noticable when I have gmail open (but maybe because I usually have gmail open).  Also noticable on CNN/MSNBC sites.
Re: When Google Chrome runs, I see 100% CPU usage! blackj85 11/4/09 3:07 PM
all -

not sure if this has been identified yet but i, too, experience this sudden increase in cpu demand and have noticed that when my cpu locks at 100%, the gmail tab in my chrome task manager goes unusually high (88-high 90's%).  closing the gmail tab takes both the chrome task manager overall cpu level and the computer's cpu level back to normal.  definitely a big disappointment as i have a LOT of use for a consistently open gmail tab...

just thought i'd pass it along.

thanks
Re: When Google Chrome runs, I see 100% CPU usage! vivekvsapre 11/5/09 11:17 PM
Hi All,

        I also faced the 100% CPU utilization issue with Chrome.

           I recently installed windows 7 and everytime I open Chrome to do anything its shoots up my CPU Usage to 100% in a matter of a few mins. The computer freezes and all I can do is hard shut down :( . Chrome is my favorite browser and not being able to use it in Windows 7 is frustrating.

Re: When Google Chrome runs, I see 100% CPU usage! Weeble 11/19/09 8:35 AM
Recently (past few weeks?), it seems that Chrome has started using a lot of CPU on GMail and Google Reader tabs. E.g., right now I see in the Chrome Task Manager:

Browser    59,376K/0/0
Tab: New Tab    7,576K/0/0
Tab: google chrome cpu usage - Google search    31,652K/27/0 (Next two entries in same row)
Tab: When Google Chrome runs, I see 100% CPU usage! - Google Chrome Help    -/-/0
Tab: Google Reader (883)    -/-/0
Tab: Google Mail - Inbox (654) - xxx...@gmail.com    28,952K/27/0
Plug-in: Shockwave Flash    11,100K/0/N/A
Plug-in: Google Gears 0.5.33.0    2,388K/0/N/A

This is after having restarted the browser very recently (within the previous 15 minutes or so).

I have Windows Vista Enterprise SP2 64-bit, running on a Core 2 Quad Q940 @ 2.66GHz with 8GB RAM.

Process Explorer shows lots of red (more than half the spent CPU time is red) in the CPU usage graphs indicating kernel mode time, I think.

I think we have Sophos Anti-virus running all of the time. It's process ("SavService.exe") doesn't seem to show any CPU usage at the moment.
Re: When Google Chrome runs, I see 100% CPU usage! Gary123456 11/20/09 4:38 AM
The high-CPU-usage problem is still happening for me in Chrome 4.0.223.16.

I typically have 3 or 4 Chrome windows open with 3-10 tabs each. They're fine for a while, with total CPU usage just 2% or so. Eventually, though--often after the PC resumes from sleep (S3)--one of the Chrome processes shoots up to 25% (full usage of one core) and stays there. Often it's either the Shockwave Flash plug-in or the Gmail/calendar/docs page (https) that's responsible. I can usually kill the offending process or tabs and then have CPU usage return to normal (for a while) even after I re-open those tabs.

What's especially annoying is that the high CPU usage prevents the PC from automatically sleeping when it's been idle. When Chrome isn't misbehaving, automatic sleep works very well.

Chrome 4.0.223.16, Win7Pro x64 (all updates installed), Avast 4.8.1356, GA-P35-DS3Lr2 (F9 BIOS), Q9450, 4GB OCZ8500.

Please let me know if I can provide any other data to help solve this problem.

even when i close google chrome there is still chrome.exe in processes that is taking 50% CPU! Help?
Re: When Google Chrome runs, I see 100% CPU usage! marchesi 1/8/10 1:47 PM
sometimes the process takes some time (~30s) to disappear. It depends on your machine horsepower, how many windows opened and stuff. Are you using chrome beta 4? The 3,stable version shouldnt misbehave like this... Also, are you using xp, installed many months ago, is the registry ok? If you thrust some registry cleaner, it could help. Did you check for virus/spyware and stuff?.. I have never seen this behaviour in an healthy machine. Please post some machine/os/config details, it would help a lot...
Re: When Google Chrome runs, I see 100% CPU usage! KDD 1/9/10 2:47 PM
I run into the CPU at 100% whenever I open a report delivered via Microsoft SQL Reporting Services 2008 - is this a known bug or is this specific to the application I am using? I get the CPU at 100% even when I open the report directly through the default web reporting site provided with SQL 2008.

I am on Chrome 3.0.195 on a WinXP machine will latest SP applied.
Re: When Google Chrome runs, I see 100% CPU usage! qutsemnie 1/14/10 3:26 PM
I noticed chrome maxing out one of my cores when I was just sitting reading a book with some browser windows open.  The chrome task manager said it was the tab with google docs open.  But I wasn't working with them, what should they be doing?  I closed one and another tab set with google docs open started taking up all of one cores cpu.  Anyway, don't got any useful info other then to say the browser has ghosts in the machine...
Re: When Google Chrome runs, I see 100% CPU usage! Viski 1/20/10 12:10 PM
I have the problem when visiting pages that have Flash or something similar, like Youtube or Facebook when certain ads load.  For what it's worth, though, Microsoft Silverlight(the video plugin for Netflix) runs perfectly.
Re: When Google Chrome runs, I see 100% CPU usage! mark.malewski 1/20/10 12:47 PM
I experienced the same exact problem with the Google Chrome "massive memory leak", even though the memory usage does not show up for Google Chrome in the task manager, my memory percentage would rise about 1% every 2 seconds everytime I opened Google Chrome.  This seems to be a Google Chrome problem.

It seems as if Google Chrome has a massive memory leak problem.

I noticed it when I went to go eat dinner, and came back and my memory usage was around 99% on 10GB of RAM!  When I shut down Chrome it went all the way back down to about 1.8GB of RAM (with all my other applications working perfectly).  Google Chrome only had 3 tabs open, and it was using over 8GB of RAM!  When I shut Chrome down, it would immediately free up the RAM and the Physical ram would drop back down to 20% again.  As soon as I opened Chrome again, it would jump from 20% to 70% (about 1 percent every 2 seconds) and then after 70% it would rise about 1% every 10 seconds until it reaches 99% of Physical RAM.

I know it's Google Chrome memory leak problem because my Ram usage only increases when I open Google Chrome.  The RAM simply gets used up and disappears as soon as I open/start Google Chrome.  So it's definitely a massive memory leak with Google Chrome.

Re: When Google Chrome runs, I see 100% CPU usage! mark.malewski 1/20/10 12:54 PM
Is Google Chrome indexing our browser cache data?

I've read Blessed Geek's "Conspiracy theories" and I do agree that something is going on with Google Chrome, and I've experienced the same "massive slowdown" of my computer as well.  I'm running a Dual Quad-Core XEON's with 10GB of ram, and it seems that Google Chrome is constantly doing something in the background.  I originally thought it was a "memory leak" because it only happens when Google Chrome is open.  I'll watch my Physical memory usage spike from 1.8GB to 9.81GB (98% or 99% memory usage) anytime Google Chrome is opened.

I noticed that if I clear out the browser cache, that it seems to immediately fix the problem.  I also have noticed the slowdown of accessing the internet (using Chrome), and also noticed that when Google Chrome is open that my computer continously accesses the internet.

These are my observations/consipiracy theories:

1) When installed initially, Google Chrome was extremely fast, the response was equally fast as well.  As I used Google Chrome more and more, it slowed down gradually (until it had gotten to the point where it was unusable).  It seems to be related to the file size of the browser cache.

2) Google Chrome seems to allow the cache size to grow to an ENORMOUS file size (18+GB to 20GB) and this seems to take up quite a large amount of disk space.  Then it seems that Google Chrome does some form of CPU/RAM intensive "indexing" in the background while the computer is sitting idle (thus preventing the computer from going into sleep mode, and keeping the RAM usage extremely high), although nothing comes up in Task Manager, and no process shows up in Task Manager I do notice that my computer's Physical Memory available jumps from 1.8GB to 9.8GB and the Physical Memory jumps from 20% to 100% usage anytime Google Chrome is opened.

3) Is Google indexing our browse cache using our local machines (using Google Chrome as an Applet for Google's Search Engine indexing?)  I noticed that as my browser cache gets large, my computer uses up more and more RAM (as if it's performing indexing of the browser cache) and it slows my computer to a crawl, even using up 100% of my system's physical RAM resources.

4) I also noticed that Google Chrome constantly tries to access the internet (every few seconds) as the browser cache file grows, thus slowing down internet network traffic and creating newtork congestion as Google Chrome is constanting transmitting traffic/data every few seconds.  Where is this traffic going, and is Google Chrome "phoning home" back to Google and transmitting any of the indexed browser data back to Google Search Engine?

In my opinion, I've been researching this "slowdown" phenonomen for several days now, and all of the reported posts seem to show the same signs of a Google "Trojan Virus", or something that is running in the background (that isn't coming up in Task Manager) that seems to use up all the system's resources.  It only happens when Google Chrome is running, and this is why I'm beginning to suspect that Google Chrome may have some type of Browser Cache Indexing virus/trojan installed that performs browser cache indexing (on our local machines) and then transmits these indexes (indexed files) back to Google (for use with Google's Search Engine Indexing).  One theory is that our local machines are doing all the web page indexing for Google, and anyone that seems to be using "Google Chrome" browser is actually doing the web page indexing (of your browser cache) thus you are updating, spidering, and indexing current web page content for Google!

As our browser cache gets larger and larger in size, it slows the computer down significantly, and the indexing of the browser cache takes up more and more RAM usage, and it gets to the point where the computer is slowed down to a crawl.  I've noticed lots of internet traffic anytime Google Chrome is opened up, as if something is being transmitted back to Google.

If you clear the browser cache, then there is nothing for Google Chrome to index, and then it speeds your computer back up again (as normal).  As you view web pages, then your browser cache grows in size, and Google Chrome slows your computer down to a slow crawl again, and Google Chrome seems to be indexing this browser cache, and I noticed when I walk away from my computer for an hour or two and come back that my CPU usage has skyrocketed and I also notice large amounts of internet traffic from Google Chrome (and my RAM usage is around 98%).  If I shut Google Chrome down, then it all stops.

This leads me to believe that Google Chrome may NOT actually have a "memory leak" but instead it seems to be doing some form of intentional web browser cache "indexing" where it indexes all of the browser cache, and it probably submits these web page indexes back to Google's Search Engine, so that our local machines are acting as "clients" for Google's Search Engine, and Google is using our local machines to perform the browsing, searching, and indexing of the internet and spidering of web pages.  As we view web pages, that data is stored in a cache file in our local machine, and it seems that Google Chrome is indexing that browser cache file, and then submitting the index back to Google Search Engine (thus creating the network congestion/slow down anytime Google Chrome is running).

This would explain the "Hosts unreachable" and intermittent ping and slow network connectivity speeds of well known sites when using Google Chrome.  It seems Google Chrome is indexing in the background, and also transmitting data in the background, and this may explain WHY Google Chrome is running so slow, and slowing down our local machines (by using up all our machine's resources, RAM, and internet connectivity).    

Are we doing the indexing and work for Google's Search Engine?  Is Google Chrome just an applet that Google is handing out, so that our computers do all the searching and indexing of websites for Google?

That's my conspiracy theory.  Why wouldn't Google allow us to disable the browser cache?  Why would Google allow the browser cache file to reach huge crazy insane sizes like 18GB-20GB in size?  Why would Google allow Google Chrome to use up 5+GB of RAM on startup?

Google Chrome is doing something, and even Google acknowledges (with it's recent poll about "Do you feel that Google Chrome is slow?") that there is something fishy going on with Google Chrome.

Does Google Chrome have a Trojan Virus installed that performs indexing of our Browser cache?  Is Google Chrome transmitting that indexed data back to Google?
Re: When Google Chrome runs, I see 100% CPU usage! mark.malewski 1/20/10 1:02 PM
Why is Google so silent about this issue, and why does Google refuse to confirm (or deny) that Google Chrome is storing huge 18GB-20GB cache files on our local machines, and Google Chrome is indexing our browsing cache files, and is Google Chrome transmitting any of that indexed data back to Google?  Is this why we see such high spikes in CPU usage, and high spikes in Physical Memory usage anytime Google Chrome is used?  Also is this why we see such an increase in internet traffic usage anytime Google Chrome is being used?  

I have no problems with any other browsers, or any other applications, and everything seems to be related specifically to Google Chrome, and even if I open Google Chrome with no tabs open, and no pages open, my Physical Ram skyrockets, and Google Chrome uses up about 5+GB of ram, and sometimes causes huge spikes in CPU usage, and if I shut Google Chrome down then it all stops.  It only happens while using Google Chrome, and the solution to the problem seems to be to delete the Google Chrome browser cache.

If I delete the browser cache, then the Google Chrome Browser (and Google Chrome Trojan Virus) has nothing to index, and nothing to use up the RAM, or CPU usage, and nothing to transmit back to Google.  So I'm really beginning to wonder if there isn't something fishy embedded into the Google Chrome, that is indexing our local machines (our local browser cache) and transmitting that indexed data back to Google.
Re: When Google Chrome runs, I see 100% CPU usage! Gobbledegook 1/20/10 11:05 PM
Isn't Google Chrome's code open source? Doesn't anyone have the technical knowledge to find out if there's something like that embedded in the code?
Re: When Google Chrome runs, I see 100% CPU usage! mark.malewski 1/20/10 11:33 PM
We'd need Google to turn over their source code for Google Chrome.  

Chromium is open source, but Google Chrome isn't.  (Google Chrome is based on Chromium).

Even if it wasn't embedded into the source code itself, they could always embed a Trojan/Malware into the installer.  I'm really beginning to believe that there is a distributed-computing Trojan/Malware embedded into Google Chrome.  It certainly would explain the CPU spikes, the overheating laptops, and the Physical Memory spikes (hitting 98-100% RAM utilization) and it certainly would explain why computers have been brought to a complete crawl that have Google Chrome running on them.  The more you surf the internet the slower and slower your computer becomes.  As you surf the web, and your browser cache size increases, I believe there's a good chance that Google Chrome is indexing that browser cache, and sending that indexed data back to Google.  Looks like Google Chrome might be a very nice "Trojan/Malware Client" for Google's Search Engine.  Using computers all over the world, to index the internet for Google.

It sure would be interesting to see.  A Google Chrome Developer could look at the source code and at least shed some light on this for us, but Google has been pretty quiet about the whole thing.  Very tight lipped, but it sure would explain what is going on (and would also explain how Google is secretively reducing it's costs per CPU cycle, and indexing the web at blazing fast speeds without increasing their data center sizes ten fold).

It would also explain how private data (behind firewalls) seems to somehow end up in Google's search results.  If Google Chrome is in fact indexing the browser cache, it sure would be a nasty thing.  I would just like Google to come forward and at least tell us if their Google Chrome browser is in fact indexing data on our local computers and indexing our local browser cache.

Google seems to be extremely tight-lipped about it all.  I've love to see what the Google Chrome developer's have to say, and if they can shed some light on this for us, and at least let us know if Google Chrome is in fact indexing our browse cache.
Re: When Google Chrome runs, I see 100% CPU usage! Gobbledegook 1/20/10 11:35 PM
Why are you constantly repeating your statements?
Re: When Google Chrome runs, I see 100% CPU usage! mark.malewski 1/21/10 1:13 AM
@Gobbledegook,

Why do you post such ignorant comments?    How would you explain a 98%-100% Physical Memory (or CPU utilization) that stops when you shut down Google Chrome?  Also how would you explain deleting the browser cache would suddenly cause Google Chrome to stop using 5+GB of RAM?  Do you have a hard time believing that Google Chrome could actually be indexing our browse cache, or that Google Chrome could possibly be transmitting the indexed files back to Google?  (for updating their Google Search Engine)  Google has embedded "distributed computing" code into their software in the past (look at Google's toolbar).  It certainly wouldn't surprise me that Google may have embedded some "distributed computing" code into Google Chrome, and Google Chrome may be indexing our browser cache files, and transmitting those indexed files back to Google (to index/spider the internet and update Google's Search Engine results)

I seriously doubt that the high CPU utilization, and high Physical Memory issues are because Google is using Google Chrome to find the cure for cancer.  ;-)

http://www.extremetech.com/article2/0,1558,288866,00.asp

Why would deleting the browser cache suddenly fix the problems?  Also why on earth would Google Chrome have a 20+ GB browser cache by default, if Google wasn't using it for indexing?  Also why isn't the cache size adjustable.  300MB should be plenty of space for a browser cache file.

20+GB just seems like an extremely large amount of space for a browser cache file, and it does seem odd that as the browser cache file size increases, the amount of Physical RAM (and CPU utilization) increases when the computer is idle.

I would just like to know if Google Chrome does in fact index our browser cache files.  There are Google Developers that could easily answer the question, and let us know if Google Chrome does in fact index our browser cache files.
Re: When Google Chrome runs, I see 100% CPU usage! Gobbledegook 1/21/10 3:43 AM
You're being redundant without my help.
Re: When Google Chrome runs, I see 100% CPU usage! mark.malewski 1/21/10 2:40 PM
@Gobbledegook, do you work for Google?  Quit trolling (if you're not part of the solution, then you're just part of the problem).

My concern is the RAM utilization (that is not appearing in task manager), as well as the high CPU utilization (when the system is idle), and also the "heart beating" and "internet traffic" that seems to be going on when Google Chrome is running.

Gobbledegook, I suspect you probably work for Google and are just another Google puppet, but if you don't have any answers then please go find a short pier and go take a very nice long walk.

You may not have the intelligence to understand the security & privacy implications if Google is in fact indexing our browser cache.  Companies (and users) download a browser not expecting any type of Spyware/Malware/Trojan to be embedded inside of a web browser.  Users download Chrome expecting it to be spyware/malware/trojan free, and not expecting their data to be indexed or mined by Google.  No user (or corporate network administrator) would expect to find a web browser that would be indexing a browser cache, and possibly even transmitting the data outside of the internal network to an external site such as Google (via encrypted channels).
I just want to know if ANY data on our local machines is being indexed, and I also want to know if Google Chrome is in fact "calling home" (and what data is being transmitted back to google).

If you close Google Chrome the "heartbeating" stops, as does the high RAM usage, and the high CPU usage.  I understand that you may work for Google Gobbledegook, but a Trojan is a Trojan.  There is absolutely no reason why people that are viewing web pages (on an internal LAN, on an internal server), and Google Chrome is still sending out heart beats?  Is Google Chrome indexing the local browser cache, and indexing these internal web pages?  Is this indexed information being transmitted back to Google?  Encrypted data seems to be getting transmitted back and forth between Google Chrome and Google.  What information is being sent to Google?
It sure would explain how a lot of private information (and stuff that was behind firewalls) sometimes ends up on Google, but I'm just asking for an answer from Google as to whether or not Google Chrome does in fact index our browser cache, and does Google Chrome transmit any indexed data back to Google?

I believe we have a right to privacy, and if Google did embed a distributed-computing client (or Trojan indexer) into Google Chrome, I would just like to know about it.  I believe anyone installing Google Chrome would want to know about it, especially if Google is bypassing their firewall, and indexing data on their personal computer!

I understand Google Chrome has a lot of "security" problems/issues, but this certainly would be among the top of the list as far as security and invading people's privacy.

There seem to be a lot of exploits and security vulnerabilities in Google Chrome:

http://www.pcworld.com/article/158400/google_chrome.html

http://www.informationweek.com/news/internet/google/showArticle.jhtml?articleID=210300297

http://www.h-desk.com/Stored_passwords_in_Google_Chrome_not_secure__t17544.html

Developers and System Administrators will not go near ANY browser that can't assure a certain level of security and privacy.

I like the speed of Chrome (which is based on Chromium), but the submission of search entries back to Google (on the address bar or search bar) and also the possibility of data mining and data indexing on the local machine, really bothers me with Chrome.
SRWare Iron seems to be a "safer" alternative to Google Chrome that is based on Chromium, that doesn't have all of the embedded Spyware/Malware/Trojans that Google Chrome seems to include with their browser.  SRWare Iron seems to be secure and respects people's right to privacy (which Google seems to be ignoring with Google Chrome).  Another alternative is "Chrome Plus" (www.chromeplus.org).  Both browsers are based on the open source "Chromium" project.  Unfortunately Google doesn't make it's source code available (for Chrome) so nobody is sure exactly what private information is being indexed and what personal data is being transmitted back to Google (in encrypted form).

http://www.kokeytechnology.com/internet-technology/srware-iron-use-the-safer-google-chrome-browser-alternativeclone/

I can't say that I'm pleased to find out that Google Chrome transmits ANY information in encoded form back to Google.  I'd really like to know if Google is in fact indexing any of the data or indexing the browser cache on my local machine.

To the security conscious among us, SRWare Iron is based on "Chromium" (the open source project) and has all the innovative features of Chrome, but lacks the security holes and security vulnerabilities of Google Chrome.  SRWare Iron also doesn't have any included Trojans, Spyware, or Malware.  It's completely open source.  It also seems to have a built-in adblocker (which blocks many of Google's ad-tracking initiatives), and doesn't have any of the embedded Spyware or "phoning home" back to Google that Chrome has.

http://www.srware.net/en/software_srware_iron_chrome_vs_iron.php

Another good alternative that respects your privacy is "Chrome Plus" which is based on the open source Chromium, but has LOTS of additional features, and "Chrome Plus" is OpenSource and also respects your privacy unlike Google Chrome (Iron and Chrome Plus also have an included ad-blocker).

http://www.makeuseof.com/tag/chromeplus-a-google-chrome-alternativ-with-some-spicy-extras/

Chrome Plus may seem like a good alternative to Google Chrome:

http://www.ghacks.net/2009/08/28/chrome-plus-is-a-custom-chrome-build-with-extra-functionality/

http://techie-buzz.com/utilites/chrome-plus-the-evolution-of-google-chrome.html

Chrome Plus and Iron are both based on Chromium without the "privacy annoyance" features of Google Chrome.

http://www.chromeplus.org/

(ChromePlus is completely Open Source, which Google Chrome is not)

ChromePlus has no Malware, and no Spyware.  It doesn't do any tracking, nor does it send anything back to Google.

http://forum.chromeplus.org/viewforum.php?f=2

Chrome Plus includes a nice "IE Compatibility" mode as well, and is based on the latest Chromium 4.x release.

As a user of Google Chrome, I just want to ensure that my personal privacy and data is protected (and that Google Chrome is not indexing any data or sending any information back to Google).

The high Physical Memory usage, and high CPU usage (and extremely high disk space usage) in Google Chrome just seems odd, if Google doesn't want to give answers than it might be best to just begin using an Open Source alternative like Chrome Plus.

http://www.chromeplus.org

I'm not saying that Google is "evil" yet, but when companies start to get large (and powerful) then the "evil" usually begins to follow.  Greed and power leads to corruption.  Ultimate power leads to ultimate corruption.

I just want to ensure that my privacy (and my personal data) is protected, and that Google is not indexing any data (or anything) on our local machines.

Re: When Google Chrome runs, I see 100% CPU usage! clement 1/27/10 2:33 AM
The bug is in Google Docs main page which runs something like every hour an operation that kills your CPU. You have to close the tab Google Search (not necessary to close FF or any other tab as opened Google Document for example). You can open again the Google Search tab and you'll be ok for the next hour. Google guys wake up.
Re: When Google Chrome runs, I see 100% CPU usage! sportymomo 1/28/10 1:56 AM
thanks mark.malewski above.

Today , i have just meet the problem of " High CPU utilization of Chrome ".

I am a big fans of chrome with its amazing browsing speed. Well this week, I use chrome as usual.
However , the computer was just going slow response to my request. I checked the TaskManager , 1 core ( total 2 ) is 100% working busy.
Therefore , the most Chrome tab i open , the more CPU rate used.

After 3 tab open , 2 cores are 100% utilized.

I search the web for solution and thanks mark.malewski ,
I remove all the browsing cache , all of them ~~!!

Yes , after restart chrome , everything backs to normal.

I have no concern on the cause , how to lead to problem and even check the source code . But I solve the problem by removing cache.
Re: When Google Chrome runs, I see 100% CPU usage! Ted.mosco 2/14/10 8:39 AM
I'm having the same issue. All tabs are only doing 0-2 on CPU usage but shockwave is doing 57-65 CPU and over 1gb of ram. When I terminate it and let it open again it sits around 0-1 CPU and 22,000kb ram.

Google version 4.0.249.89 unknown (38071). I would say just blame shockwave but doesn't firefox use them? I'm having no issues with their browser, or any other program using shockwave.

Windows Vista, up to date. Q6600 Quad core processor, 4gb ram.
Re: When Google Chrome runs, I see 100% CPU usage! IgsmorphF 2/16/10 8:46 AM
- What version of Chrome do you have?
(4.0.249.89)
- What operating system are you running? Please include as many specifics (like service packs) as you can.
XP Pro w/SP3
- What hardware are you running? How fast is your processor? Is it single or dual core?
Intel Core2 T7600 @2.33GHz, 2GB RAM
- What other software are you running? Do you notice any mysterious processes in your Windows Task Manager?
Google chrome is using about 12% of my CPU with one window and 4 tabs.  None are streaming audio or video.  
All other applications are using less than 1%.  FF never used more than 2-3% even with video streaming.  Unless there is a fix, I will switch back to FF.

Re: When Google Chrome runs, I see 100% CPU usage! woodelf 2/20/10 12:01 AM
I'm running ver 5.0.307.9 beta - from 'http://dl.google.com/linux/deb/' on Debian 'testing' at home on an 'old' 1200MHz Pentium laptop with 512 MB ram and at work again on a laptop but with dual core cpu and over 2 GB ram on XP (SP3), in both cases after a few mins its using 100% cpu, which ceases once Chrome is closed.

This is unfortunate since I'd grown to prefer Chrome over Iceweasel (Firefox) in some ways, but if this issue can not be resolved soon - looks like this threads been going for over a year(!) - then it'll have to go.

Shame really...

Re: When Google Chrome runs, I see 100% CPU usage! sierraseven 2/24/10 1:58 PM
"kinda scary nobody from Google have commented on this"

Bah hah hah ha!

After apparently too many posts critical of Chrome, I got an email chastising me for my "attitude" and telling me that this forum is NOT intended to offer solutions from Google - it's a USER forum, where Chrome users can - what was the phrase they used - something about coming together as an online community and sharing tips and tricks, blah blah blah. The told me to go to the developers' forum for fixes - but not being a computer geek at the level of being able to write code, I could not understand much of what was being said, and it didn't look like there was any useful advice for the average user. Apparently you can change some settings on your computer, download new updates every night, make changes to your anti-virus program, change your firewall settings, on a daily basis based on advice from those who like to tweak their computers and browsers constantly. Myself, I much prefer a browser that is more of a finished, consumer-ready product - I don't really enjoy making changes to my computer every day, although I know there's some folks that do.

So, no, Google is not going to fix any of this - and if you're just an average user who wants a browser that works without having to constantly tinker with it, you are out of luck with Chrome.

I am also getting a high CPU usage on chrome.  Occasionally some of the tabs will use about 25% of my CPU each.   Not every tab does this.  None of the tabs are using flash.  If I close the browser and restart it, the tabs take near 0% again.  Then after a few minutes they return to 25% usage per tab.

I have the AdBlock and Browser Button for AdBlock extensions installed.  Here is some specs of my system.

Chrome 4.0.249.89 (38071) on WinXP SP3 Intel Core 2 Quad CPU @ 2.4 GHz 3GB RAM

I have figured out that it is certain sites that cause this CPU chomping.  In my case it was a MS SQL Server 2008 Reporting Services site.  Mozilla Firefox displays it fine without the CPU crunch.  Perhaps other sites cause the same behavior.

I'd like to add myself to the long list of people experiencing this problem. When I first start Chrome, it's fine, but at some time, I can shift-esc to view the task manager and see that the browser (not any of the pages or extensions) is constantly running my CPU at around 50%. What could it be doing? Seems like it's clearly an issue in the browser that needs to be addressed.

I run Windows 7 Home Premium 32 bit with 3 GB of RAM and a Core 2 Duo processor @ 2.4 GHz
Chrome version is 4.1.249.1036

I had been running Google Chrome for about 6 weeks with no problem. I though it was great. I use several applications that require the use of Flash Player. So discovering Chrome was wonderful. Chrome significantly improved page loading time, and I could load about 12 tabs with flash content with no problem. Then last weekend, the flash player began to crash on every tab. Then a couple days ago I noticed that Chrome was not only locking up, but once I managed to exit the browser, I had trouble opening other applications and browsers. My first two hints that something was very wrong, was when CCleaner informed me that I still had Chrome open, when I did not. In addition, my computer was frantically working, which led me to open Windows Task Manager and discover that Chrome was using memory into the 6 digits despite the fact that it was closed. I have looked for answers to the problem, and tried all things suggested. Nothing has work. I will be sad to lose this great browser, but I can't seem to find an answer that works:
Opened Task Manager to find offending page. Doesn't really work because the whole browser is locked! Clear cache: nope.
Close browser. Nope, still tying up memory....What next!

I'll voice in here too.  Whenever I do *anything* in Chrome, one of my CPU cores jumps to almost 100% usage and stays there.  And when I say *anything* I mean this:

1. Launch Chrome
2. Watch the Windows Task Manager and wait for the CPU to settle after the initial load, goes to 0%
3. Click on address bar and type "www".  I don't press enter or click anything, I just type the three letters 'www'.
4. one instance (of two) of chrome.exe jumps to 25% CPU (I have a quad core)
5. Launch the google task manager and the "Browser" page sits at 25% CPU and stays there

I've been using chrome for a good 6 months and I don't remember noticing this before.  I noticed it now because it got to a point where after 30-60 minutes of usage, my typing started getting delayed when using gmail.  I've tried all kinds of things to try to get around this including clearing all caches, uninstalling and re-installing both the beta and stable releases, uninstalling all add-ons (I was running the gmail, wave and google apps add-ons before).

My specs are:
Windows 7 Ultimate x64
Dell Optiplex 755
Intel Core2 Quad CPU Q6600 @ 2.4Ghz
4GB of RAM
Chrome 4.1.249.1036 beta (41514) (also tried with latest stable version as mentioned)

Chrome was a breath of fresh air coming from FireFox, but this issue has pushed me back to using FF.
Re: When Google Chrome runs, I see 100% CPU usage! dotcominfo 3/24/10 8:12 AM
Here's a little extra info, for what it's worth...

Yesterday, I was playing around with this and noticed that the CPU utilization in Chrome is typically calm until I visit a site with flash on it. Then, from that point on the "browser" line in Chrome's task manager goes up to and stays at about 50%, no matter if I navigate away from the site with flash or close the tab.

This morning, I was noticing that this problem never occurs on my 64-bit laptop, even though it is running the 32-bit latest stable release of Chrome. Weird....

My problem occurs without flash.  I don't even leave the new tab page.  I thought that perhaps the thumbnails were triggering flash but now I have google.com as my home page and I still have the same problem.

Hi everybody,

We understand that high CPU usage is a very important issue and we're working to get to the bottom of it. This thread was started a long time ago, and the conversation has evolved a lot since the first post. I'm going to try to separate your different issues out.

If you are on the most recent version of Google Chrome and you can consistently reproduce high CPU usage with specific steps, please go to the link in my references that fits your specifications and follow up on that thread. So that we can troubleshoot, be sure to include the following two things in your post:

1. Google Chrome version number (Tools > About Google Chrome)
2. Steps to reproduce high CPU usage

I'm going to close this thread so that we can have more focused conversations on those different threads.

Best,
Blair
