High CPU Usage - Mac Blair (Googler) 3/29/10 2:39 PM
Are you experiencing high CPU usage when running Google Chrome on your Mac?  For us to troubleshoot, please include the following two things in your post:

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

Best,
Blair
Re: High CPU Usage - Mac gd2440 4/1/10 12:41 PM
Chrome 5.0.342.7
OS X 10.5.8

Never had this problem before today, so came onto this forum.  Shockwave Flash plugin running cpu at 100+.  I usually have 2-3 browser instances open, each with 6-10 tabs.
Re: High CPU Usage - Mac Brodster85 4/1/10 1:27 PM
Chrome 5.0.342.7
OSX 10.6.3

Same here - Shockwave Flash plugin hovers ~ 100% CPUusage.  This site I visit has music streamers that I assume is flash and it hangs for so very long.  Also noticed most websites loading very slow in general -  I can't scroll through many pages unless they're completely done loading.  Looking forward to a fix.  :)
Re: High CPU Usage - Mac lardissone 4/1/10 3:37 PM
Yes, it happens also with sites with many Youtube videos embedded. It takes some time for each embed.

Re: High CPU Usage - Mac Brodster85 4/1/10 7:10 PM
Uploading a picture, it's small..8k...to tinypic.com produces this annoyance as well :)  It will stall out and ask if I want to kill the page or wait, I click wait and it works at it for a bit more and finally completes the process.
Re: High CPU Usage - Mac Brodster85 4/2/10 6:52 AM
ATTN:  From another thread on this help forum I read about disabling adblock in extensions.  This seems to have worked!  Of course I'd like to have Adblock enabled :)  This quickfix will do for now.
Re: High CPU Usage - Mac Bluemaruti 4/10/10 1:59 AM
I'm running Chrome version 5.0.342.9 beta on OSX 10.6.3 on a MacBook.
Only noticed the high CPU usage today.  It seems to be whenever I open a tab for the BBC homepage (I live in Europe so have the non-UK BBC page running their beta site (http://beta.bbc.co.uk/).  CPU usage for Shockwave Flash and Google Chrome Helper leaps up towards 90%.
No extensions on Google Chrome - so not a problem with Adblock
Re: High CPU Usage - Mac cwkhawk 4/12/10 4:48 PM
ver: 5.0.371.0 dev
There is the Chrome app which is running at about 10%, and then there are two Chrome Apple Scripts running at 80% and 50% each. Like others, the problem only exists with web pages running Flash.
Re: High CPU Usage - Mac echaiphus 4/13/10 3:18 AM
ver. 5.0.342.9

imac intel osx 10.5.8
Shockwave Flash (Chrome Plug-in Host) 50% cpu
Chrome and chrome helper about 1% cpu

streaming video bumps cpu usage up to about 75-80%, and i've noticed that some video sites (especially hulu) freak it out, where the video will freeze, and the audio will continue to play. It won't stop, even if i force quit the program. the only way to make it stop is to restart my computer.  don't know if this is related or not, figured it couldn't hurt to mention.
Re: High CPU Usage - Mac gu3miles 4/13/10 2:51 PM
Same thing happens to me. iStat Pro showed 4 "chrome processes" running. It would take up about 60% of my cpu. I tried existing chrome, force quit, chearing cache, and cookies (sad day). Nothing worked. I restarted. Its back down to where it should be, but there are still two processes running, so I'm assuming the problem will come back.

This used to happen all the time, but then quitting chrome would fix it. I recently installed flash 10.1, so thats the first time the force quit didn't work. Its that or the google find in text extention.

Ver. 5.0.342.9 on a 2007 Intel core 2 macbook pro 15".
OSX 10.6.3

Ya'll should fix this.
Re: High CPU Usage - Mac gu3miles 4/13/10 3:45 PM
I used to have Nortan Anti-Virus software installed, which I thought I had deleted, but there were still reminants remaining. I went to symantec.com and got the full uninstaller. It found the leftover files, and now chrome seems to be working correctly. while cpu usage is still high when using flash (cause flash sux on macs), its not remaining at a base level. when I exit the flash site, cpu usage drops backd own to where it is supposed to be.
Re: High CPU Usage - Mac prescod 4/13/10 10:21 PM
My wife says she has the same problem every day when she tries to work on Flickr. It's really ruining the switch to Chrome, which was previously great.

11 tabs open - one window - NO flash
75% cpu usage

switching back to safari.. sigh
Re: High CPU Usage - Mac SiFi 4/14/10 12:05 PM
Same issue for me.  Clearing all browsing history doesn't help.  Seems only to be when a tab is using Flash.

Chrome 5.0.342.9 beta
OSX 10.6.2

site examples:
adobe.com spikes the CPU but not all the way.
radiotimes.com almost maxes out the CPU continuously.
Re: High CPU Usage - Mac staticfloat 4/15/10 9:19 AM
I have a strange problem.  When I APPLE-CLICK a link to download a file, and keep that tab open, I get 100% CPU usage from the "google chrome helper" process.  Even after the file finishes downloading, the CPU usage continues.

I'm running OSX 10.6.3, Chrome 5.0.342.9 Beta.
Re: High CPU Usage - Mac shortspecialbus 4/19/10 7:35 AM

Re: High CPU Usage - Mac Blair (Googler) 4/19/10 8:36 AM
Hey everybody,

Is your Shockwave Flash updated to the most recent version? If not, could you try updating and let me know if that helps?

Thanks,
Blair
Re: High CPU Usage - Mac Bluemaruti 4/20/10 2:13 AM
Hi Blair
I have the latest Shockwave Flash.
CPU usage when playing a Flash video on the BBC site (only place I've checked) goes up around 70%, split between Google, Google Chrome Helper and Shockwave.
On a secondary note, as I don't understand these things, is it right that I should have 5 processes called "Google Chrome Helper" running at the same time?  (PIDs are 3114, 3117, 3118, 3119, 3120.)
Chrome version 5.0.342.9 beta on OSX 10.6.3 on a MacBook
Thanks
Re: High CPU Usage - Mac nlflux 4/22/10 11:15 AM
Chrome for mac "5.0.342.9 beta" & Flash videos (youtube etc) always hitting 70%+ cpu usage & 70 degrees Celsius :(
Re: High CPU Usage - Mac abdu 4/26/10 12:50 AM
5.0.342.9 beta
Mac OS X 10.6.3

I just have to play a MegaVideo video and the plug-in takes up about 60% of spu and my fan runs at 5000rpm this started happening about 3 days ago.
Re: High CPU Usage - Mac uniacid 5/7/10 5:36 PM
I have also noticed this problem with Chrome 5.0.375.29 and OSX 10.6.3, when watching actual flash video, cpu jumps to 75%+ sometimes 100%+ and the temps will run up also to 70c...

Anyone know whats up?!
Re: High CPU Usage - Mac zizousama 5/12/10 9:10 AM
Ver. 5.0.307.11 beta on OSX 10.6.3


I have three tabs open with no videos on any of them and I have ten chrome helpers running! When I play a video or two, cpu usage goes to 70+%. This is the most frustrating thing ever. It practically keeps me from using chrome at all as it kills my cpu with a simply video.
Re: High CPU Usage - Mac Blair (Googler) 5/13/10 5:22 PM
Hey guys,

Have you tried clearing your browsing data, specifically your cache? Other people have said this solved the problem for them.

Cheers,
Blair
Re: High CPU Usage - Mac Willvalleysports 5/17/10 9:38 AM
5.0.375.38 beta on Mac OSX 10.6.3
I open any flash page and Activity Monitor shows it running from 90% to 119% and my fan goes nuts.  Burned through 2/3 of my 8 hour battery in about an hour.  Chrome uses about 20% and then the Flash plugin uses 90-120.  I tried clearing my cache, and even deleted all stored data in flash from the same settings page, then the adobe website.
Re: High CPU Usage - Mac tmorgan987 5/19/10 1:00 PM
Everything had been running fine (with same version and same extension [yes, just one] loaded), but I closed and relaunched Chrome today to free up some RAM. (Separate issue, but something bad is going on between Chrome and OS X, resulting in Chrome eating up 3-8 GB of RAM. Seems that Chrome leaks memory slowly over time and then once it hits swap the first time, memory usage balloons.)

When Chrome was relaunched, I encountered the 100% CPU problem. In my case, it is not flash -- Activity Monitor shows usage semi-evenly distributed across each of the Google Chrome Renderer processes. I just relaunched to see if that'd help, but no dice. So, I cleared the cache and relaunched -- no difference. I disabled the only extension I have, Flashblock, and still no difference (except that flash was now taking up a few percent of the CPU itself -- nothing huge though).

I will note that I was running just over 100 tabs across about 8 windows. I started shutting those down a few at a time and found that the overall CPU usage declined linearly with the tabs being closed.

So, it appears that in my case, each tab is sucking down 1-2% or so of the system CPU. This shutdown process was performed with Flashblock still disabled.

OS X 10.6.3
Chrome 6.0.401.1 dev

In the past I have had Chrome suck down 100% of the CPU (on various versions, including some of the primary beta releases). However, until today I've always had luck just shutting down Chrome and relaunching.
Re: High CPU Usage - Mac tsuna 5/24/10 4:54 PM
Chrome 6.0.408.1 dev on OSX 10.6.3 with the FlashBlock extension [1]
Each tab is taking 1 to 3% CPU, which is waaaay more than what Chrome used to consume a few weeks back.  Right now Chrome is keeping both of my cores 30-40% busy on my MacBook Pro, whereas it used to be taking 5-6% in total with roughly the same number of tabs.  Sounds like a big performance regression.

Re: High CPU Usage - Mac jbverschoor 5/26/10 2:58 AM
6.0.408.1 dev on 10.6.3
On macbook with gma-950. I see around 85% cpu usage (after restoring my tabs.. it used to be after a while)
load is around 4 :S, temp 80-85 celcius, which is why my cpu won't go up

I have installed a flashblocker. That helped improve stability, but didn't fix the cpu stuff.
I also see a lot of Chrome Renderer Processes which each up between 2.5 and 4% cpu each.

Maybe you guys should look into:
javascript timers, animated images (timers), some main loops, maybe there's some polling going on here and there.
I see no unnecessary screen redraws with quartz debug.

afaik, a tab should consume 0% cpu, because all elements should be waiting.
Re: High CPU Usage - Mac Tomnibus 5/26/10 12:11 PM
I've got 6.0.408.1 dev with OS 10.6.3

I have noticed in the last few weeks that my Macbook Pro has been running it's fan over and over and over heating. I found out that with Google Chrome running IDLE not doing anything the Google Chrome Renderer program uses 28 - 30% CPU usage just sitting there.
Re: High CPU Usage - Mac j_b_m 5/26/10 3:15 PM
Chrome 5.0.375.55
OSX 10.5.8 on a 2009 Macbook Pro

CPU running consistently ~105% and 80 degrees.
Activity monitor says Shockwave in Chrome is it. Even when Chrome is not open. Running NO other programs.
Cleared cache and data, even disabled flash. No help.
Switch to Chrome was previously good up until a few days ago.
Uninstalling and back to Firefox so I can get my computer back...

Seems like this is pretty common...!
Re: High CPU Usage - Mac cfarivar 5/28/10 12:55 AM
I'm having the same problem.

Chrome 5.0.375.55
OSX 10.6.3 on MacBook 2.4 GHz / 4GB RAM

Clearing all the cache seemed to help. I'll keep monitoring.
Re: High CPU Usage - Mac cfarivar 5/28/10 1:02 AM
Hrm. Now I'm up to 4300 rpms and climbing…I've tried resetting the SMC power manager.
Re: High CPU Usage - Mac cfarivar 5/28/10 1:18 AM
Basically as soon as I start Chrome, even with just one or two tabs open, my fan starts steadily climbing. When Chrome isn't running, I'm at around 1800 rpm. Right now, I'm hovering around double that.
Re: High CPU Usage - Mac zeroality 5/29/10 1:56 AM
Hey, I couldn't find a topic for Windows regarding this problem so I'm going to post it here and hopefully someone can point me in the right direction.

Chrome 5 has just crashed for the second time. First time, I opened Windows task manager and it said it was using a whopping 400+ MB of RAM and my pagefile was well over a gigabyte. I had to terminate the process, then end the task so the GUI would close itself.

Second time, I took screencaps and it shows an unbelivable 548,128 K of RAM usage and my pagefile is 1,603M. It also shows CPU consumption at 92% for the single chrome process. It was a simple Chrome window with 4 tabs open - vBulletin (view thread), vBulletin (template editor), vBulletin (template editor), vBulletin (stylevar editor).

This is getting ridiculous and is forcing me to use Firefox. FIREFOX. Why???
Re: High CPU Usage - Mac ishermandom 5/29/10 3:48 AM
@Blair Tried clearing my cache -- still seeing the same high CPU usage

(also tried disabling all extensions -- that also didn't help)
Re: High CPU Usage - Mac zmre 5/29/10 7:41 PM
I am also having this issue with the current version (6.0.408.1 dev; mac 10.6.3).  I did not have this issue in earlier versions.  Right now, with only one tab open to www.google.com and all extensions and plugins disabled and cache cleared, Chrome uses 25% CPU.  Open a few more tabs to any sites, and I'm quickly up to 100% CPU on my '09 Macbook Pro.  

I've gone a few steps farther than most people in this post under the assumption that some file is corrupt in my Library/Application Support/Google/Chrome directory.  I separately removed each and every file in that directory and subdirectories and tried restarting Chrome after each one.  

Things improved a little bit after removing the preferences file, but right now, even if I use an alternate profile by making a Library/Application Support/Google/Chrome/Alt folder and start chrome like this:

exec /Applications/Communications/Google\ Chrome.app/Contents/MacOS/Google\ Chrome --user-data-dir="Alt"

www.google.com still uses 25% CPU.  My computer has plenty of speed and available RAM and HD space.  The vast majority of the CPU usage is "system" and not "user".    Activity monitor shows "Google Chrome Renderer" with 5 threads, 52.9mb, and 25% CPU.  I sampled the process and when displaying by Percent of Thread, it shows mach_msg_trap as taking up the vast majority of the thread's time.  The call stack is something like:

ChromeMain->ChromeMain->ChromeMain->…->CFRunLoopRunInMode->CFRunLoopRunSpecific->__CFRunLoopRun->mach_msg->mack_msg_trap

Looking at the info, the context switches and number of mach system calls are growing very, very fast.  Happy to provide more data if it might help.
Re: High CPU Usage - Mac gstein67 6/1/10 9:34 PM
I restarted Chrome (408.1) and it reopened my 60-some tabs (hard to count). They are spread across 20-some processes, and each process is taking a small percent, and in total sucking up nearly 100% of both CPUs on my '08 MBP.

After the reload, I killed the Flash plugin process. This is just Chrome hanging around sucking CPU.

Earlier versions easily supported this tab count with no CPU usage.
Re: High CPU Usage - Mac telarmago 6/1/10 9:51 PM
408.1 continues to use 25% more CPU than Safari to render Flash videos. Using latest nightly of Chromium, and the problem remains.

After a few hours of normal working (opening and closing tabs), Chrome jumps constant over 90% and besides killing / restarting nothing helps against it.
Re: High CPU Usage - Mac roadsider 6/4/10 6:53 AM

Re: High CPU Usage - Mac ibilln 6/4/10 8:12 AM
Same-o.  6.0.422; 10.6.3.  I'be been seeing huge cpu from Chrome for a while.  Last night, over night, of course no activity, it seemed to calm down.  Now, it's down compared to previous versions, but with all processes, still up to in the neighborhood of 30% cpu, macbook pro 13" 2.26 ghz.  In the past days I've been driven to use Safari, of all things!  Grump...  Tabs disappearing off to the right, tabs closing when you mistakenly click the favicon, and all.  But it's better than under 3 hours of usable computer on battery.

What's the deal with flash built-in?   I guess you might save some on IPC - or, will -all- processes use up a lot of cpu?  Sigh.  I guess for a while it will be a choice between dragging the dead whale of Safari down the beach, or, using up all your energy trying to drag the extra-lively chromefish onto the beach.

Same problem today.  Never noticed before.  Chrome started freezing while loading webpages (lifehacker.com; huffingtonpost.com) and computer was running hot.  I went into activity monitor to see what was causing the high level of processing and saw Shockwave Flash Chrome plugin cranking the CPU to nearly 100%.

Re: High CPU Usage - Mac Bluemaruti 7/1/10 1:58 AM
Afraid this problem, and the fact the Chrome cancels shutdown all the time (see http://www.google.com/support/forum/p/Chrome/thread?tid=061fae5ce3b577fd&hl=en) means I've given up on it and gone back to Safari!

61 M - 24 M for google chrome renderers
46 M for google chrome

After adding and removing tabs for a few hours and then going back to the starting tabs
170M for shockwave flash (I open tabs with flach but then deleted them...why is this still so high)
87 M - 31 M for goole chrome renderers
60 M for goole chrome

My questions is why do these increase over time (even if I go back to having the same beginning tabs)?  It seems I have to close and reopen every so often to stop the memory from filling up.
Re: High CPU Usage - Mac jonathanlrand 7/22/10 8:02 PM
Chrome v 5.0.365.99

Open any site using flash.  Multiple instances of Google Chrome helper each taking up to 40% of cpu.

Interestingly - the CPU will sometimes drop down if I don't actively use the flash applications after about 10 mins or so.

Love chrome but this is a deal breaker.
Re: High CPU Usage - Mac The Weez 8/2/10 1:58 PM
1. Chrome version 5.0.375.125
2. Basically, just having Chrome open results in 90%+ CPU usage. This is with one window and 4-8 tabs open, and none of these are using Adobe Flash Player, only HTML/CSS and some light Javascript. This is a recent occurrence, perhaps originating in the last week. I have not kept track of Chrome updates but perhaps there was one recently? This problem did not occur on previous versions of Chrome.

I was in love with Chrome on the Mac since trying it about a month or two ago, but I can't punish my 2007 Macbook Pro like this. Safari and her new extensions will have to do, unless it gets fixed.
Re: High CPU Usage - Mac Cjsnet 8/2/10 11:32 PM
Just started today for some reason, after months of happy use.  No new extensions installed!

1. 5.0.375.125
2. Just open Chrome and bam - 100% usage on Mac
Re: High CPU Usage - Mac aurichie 8/4/10 4:02 PM
Just started happening for me too since the last couple of days. The issue appears to be with how Google Chrome and the Shockwave Flash plugin are communicating with each other on Macs.

1. Google Version: 5.0.375.125
2. Surf to http://live.twit.tv stream use any of Bitgravity (400kb/1mbps) Ustream or Justin.TV and the CPU shoots up for both Google Chrome Renderer and Shockwave Flash (Chrome Plug-In Host).

After 1 minute or so, the CPU fans start to spin frantically on both my MacBook Pro (2.8GHz C2D, 4GB RAM) and 27" iMac (i5/12GB RAM) and a tremendous amount of heat and noise starts to generate. Quitting Google Chrome solves the issue.

--- SOME NUMBERS OUT OF ACTIVITY MONITOR:---

Playing any live.twit.tv video live stream in Google Chrome after 3 minutes:
Google Chrome Renderer 67.8% CPU reported in Activity Monitor
Shockwave Flash (Chrome Plug-In Host) 60.4% CPU reported in Activity Monitor

Playing the same live.twit.tv video stream in Safari is less CPU intensive after 3 minutes:
Flash Player (Safari Internet plug-in) 54.4% CPU reported in Activity Monitor
Safari 22.1% CPU reported in Activity Monitor

I hope that helps!
Re: High CPU Usage - Mac Cjsnet 8/5/10 8:51 PM
To hell with this, I just moved to Safari 5 with its extension support.

Such a relief to be rid of Chrome!

Sad, I fell the same way about the buggy Google Nexus One too.

Google, you’re lose customers hand over fist with all these unresolved far too lonnnnng standing bugs - do you realize that?  This is just the beginning…

Goodbye Chrome - for me it’s the end.
Re: High CPU Usage - Mac stoavio 8/5/10 10:12 PM
Ditching Chrome. This is ridiculous. I thought Google had the browser game figured out but this thing is nearly unusable. Running Chrome on a $2,000 laptop with bleeding-edge hardware shouldn't result in browser crashes and system slowdowns like this.

Back to Safari and Firefox I go.
Re: High CPU Usage - Mac Sidney23 8/6/10 3:54 AM
My computer is going to have a short life if I continue with Chrome. I'll switch to Safari for now.
Re: High CPU Usage - Mac Klian 8/6/10 3:57 AM
Im having some problems with Chrome too... in my case its not the CPU but the memory used.

It uses 1GB or 1.5GB of real memory with just two tabs opened and no flash.... :(

It's getting worrisome. I can't do anything else. Might ditch chrome if this doesn't get fixed soon.
Re: High CPU Usage - Mac iknowthis 8/25/10 9:12 AM
i will tell my experience, chrome runs really fast, the fastest browser around, (im on mac) BUT cpu is just tooo much.. i have the latest built. flash is just killing everything, interesting enough i tried to test same web pages with safari... well safari seems to be a little bit slower but MUCH MUCH more friendlier with your cpu and ram, so... i dropped chrome for next update.. hope you will fix this issue.

This is such a joke.  I love chrome on windows and mac, I just got it set up perfectly on both and then a new update came out that makes flash run my 2010 MBP 13's CPU at 50% non-stop!

Thanks for making a great free product, but something like this really needs to be addressed and it's all related to the built-in flash player.  Just roll us back a version or two before flash went to hell and we'll deal with any extra bugs, because none were as bad as this flash problem!
Re: High CPU Usage - Mac eyalron 9/3/10 6:57 PM
Process 'Shockwave Flash (Chrome Plug-in Host)' CPU at 100-135% after opening a page with Flash.

Same here, it's started happening since I upgraded from v5.

Currently running:
Chrome 6.0.472.53
Mac OS X 10.6.4

Task manager tells me the Plug-in: 'Shockwave Flash plugin' is the main problem.
I generally have around 30 tabs open in various windows, so there will be a lot of Flash apps running! - But no more than when I was using v5, when CPU usage by Chrome was within acceptable levels.
Re: High CPU Usage - Mac robnet 9/6/10 2:21 AM
Additionally, it seems fine in Chrome version '7.0.503.0 dev'
Re: High CPU Usage - Mac Hrshycro 9/7/10 12:41 AM
@robnet

Going to check it out.  Hopefully LastPass works with the new dev build.  Safari is driving me crazy, but chrome stable makes it so I can't even use my macbook pro 2010 on my lap.

Damn flash is always causing problems everywhere in life, or so it seems.

Re: High CPU Usage - Mac raviteja969 10/3/10 9:31 PM
Using Chrome version 6.0.472.63. I have a huge spike in CPU usage . It gets worse especially when using google maps while zooming in to locations when cpu usage goes to 60%-70% and fans start to kick in. When using safari cpu stays around 15%-25% on the same site even when i zoom. I have MacOS X 10.6.4.
Re: High CPU Usage - Mac ishermandom 10/5/10 9:29 PM
At least one culprit seems to be fixed in version 7 -- see http://code.google.com/p/chromium/issues/detail?id=57669 .  This version is still in beta, which means it is less polished and stable than a final release.  With that in mind, you can try it out here: http://www.google.com/intl/en/landing/chrome/beta/ .  Alternately, you can wait a few weeks until the stable version is released =)
Re: High CPU Usage - Mac mikeford77 10/6/10 9:26 PM
I started noticing my fans running hard a few months ago. Activity Monitor showed the browser using almost 100% CPU. It started with Firefox, so I switched all possible browsing to Chrome. Then after a while Chrome started doing the same. It is increasing in frequency and extremely frustrating. Happens on many sites( http://www.careerbuilder.com/JobSeeker/Jobs/JobDetails.aspx?IPath=OCSGCM&ff=21&APath=2.21.0.0.0&job_did=J8G1CP6N732LD2RPRFD ) with one chrome window and as few as two tabs. If I close chrome or the bad tab cpu and fans go back to normal.

MacBook Pro 2.33Ghz core 2 duo, 2 gig ram, OS X 10.5.8, latest Chrome: 6.0.472.63

I have tried removing chrome along with all related files in library an user folders and installing fresh.
Re: High CPU Usage - Mac StevenCee 10/7/10 7:42 PM
I'm using Chrome 6.0.472.63   on Mac 10.6.4

It' shoots way up, usually when a video is running, but then sometimes comes down five minutes later, even with the video still playing.  It's crazy, as Shockwave Flash (Chrome Plug-in Host) will be at the top (100%), followed by Google Chrome Renderer (19%), & then Google Chrome (14%)..... What is up with all this? I don't even have that many tabs open, & no other browsers...
Re: High CPU Usage - Mac dylanlaughlin 10/8/10 11:49 AM

Re: High CPU Usage - Mac jujumac 10/14/10 10:04 AM
Chrome v6.0.472.63
2008 MacBook running OS 10.5.8

CPU usage is consistently over 80%, sometimes to 117% (!!!) even when I am doing nothing at all with it and it is open to a text-only page (no videos, ads or anything). Tried clearing browser history- that fixed it but only for as long as the history was deleting, then the CPU and fan went crazy again immediately after. This problem only just started happening in the past few days though I have been running Chrome for a couple of months now. Restarting Chrome doesn't help as CPU and fan jumps up again as soon as I start it up. Flash does not seem to be the problem, at least in this case- only 0.1% CPU for that. Any thoughts?

Running basically any flash website CPU usage goes up a bunch, and battery life goes down. The past few days I also noticed that my battery life was extremely low so I checked activity monitor and I saw Shockwave Flash (Chrome Plug-in Host) at around 100% CPU, even when I had quit Chrome.

Mac OS X 10.5.8

General browsing, multiple tabs (usually 3 or 4), with and without Flash. At least once a week, CPU usage will spike over 100% when opening a new tab. Status bar always says "Waiting for cache..." Once that happens, Chrome remains responsive, but clearing the cache does not work and some pages become unresponsive, with CPU usage remaining over 100%. I tested it once and the CPU usage stayed at 100% until I force quit an hour later. Lately, it's been nearly a daily occurrence. Even regular clearing of the cache doesn't work.
Re: High CPU Usage - Mac rpcohen 11/16/10 10:09 AM
Having the same problem with high CPU usage on a 2007 Macbook running OS X 10.6.5 using Chrome: 8.0.552.200 beta.  It always happens on the following site: http://tmz.com as well as someothers.  

The Activity Monitor shows just one of the instances of the Chrome Renderer sucking up 80-98% of the CPU while the Shockwave plugin only draws between 1.5-2%.  I completely cleared the cache but  that made no difference.
Re: High CPU Usage - Mac frobozz 11/22/10 9:39 AM
Using Chrome 7.0.517.44 on Mac OS X 10.6.5. 3Ghz Core i7 iMac with 4Gb RAM. In activity monitor I notice that "Shockwave Flash (Chrome Plug-In Host)" is constantly at 22%-26% when NO videos are playing. If I play a video then the CPU utilization goes all over the map, hitting 80-90% often. I do not have this problem on my WIndows 7 machine. Furthermore when the playback is switched to full screen, you often get skips or freezes even if their is no motion in the video (like listening to a song and all you see is the album cover that is a static image).

Re: High CPU Usage - Mac JDENredden 12/7/10 8:55 PM
Go to Task Manager or Activity Monitor, and kill the Chrome process that is using the most CPU.
Chrome should tell you what extension crashed.
That extension is what’s making Chrome high CPU.
Uninstall that extension and you’ll be fine. :)

Re: High CPU Usage - Mac StevenCee 12/16/10 4:33 AM
JDENredden, According to the extensions window I have none installed, yet my Chrome has been out of control, with one of the flash-based plug ins (I believe it was the Shockwave Flash)alone going way over 100%. I did go to Activity window and force quit it, which helped. But it's also showing I have Google Chrome Renderer (whatever that is) 24 times in the process window! What does THAT mean?
Re: High CPU Usage - Mac ishermandom 12/17/10 3:51 AM
@StevenCee: It's prefectly normal to have a bunch of Chrome Renderer running at the same time -- usually, you'll have one per tab that is open.  Running different renderers (roughly, websites) in different processes is one of the ways in which Chrome is able to provide improved security guarantees, as this way websites can't easily muck with each other.
Re: High CPU Usage - Mac JDENredden 12/17/10 4:06 AM
The ChromeRenderer has at least one per tab, I believe. Shockwave player on a Mac can eat allot of CPU. I suggest trying the quit that process so Flash player crashes, and start again. If that doesnt work, try installing the beta version?

Don't need to do anything in particular.  Chrome and Chrome Renderer seem use high CPU in Activity Monitor whenever I'm running Chrome.

Also, in Chrome Task Manager no extension seems to take much CPU - just the "Browser" and open tabs.
Re: High CPU Usage - Mac rpcohen 12/20/10 6:34 AM
This problem does not appear to be specific to Flash on the Mac since Firefox handles the same content without similar problems.  In fact, I've gotten into the habit of automatically switching from Chrome to Firefox in order to view video content on my Mac.  Chrome for Mac should be fixed to enable it to handle video as well as Firefox does.

I've seen it at fanfiction.net as one example. MacRumors, Reddit and Newgrounds.  Oddly enough, Newgrounds, a fairly flash intensive website, doesn't spike nearly as fanfiction.net.

Re: High CPU Usage - Mac StevenCee 1/16/11 8:25 PM
Using 8.0.552.237  , all I have to do is open Chrome, and it's got Chrome, @300 - 500MB of RAM,  Shockwave Flash PlugIn @ 500-700MB, & then as many as 30 or more separate listing of Google Chrome Render @ 25 - 70 MB each, in my Activity Monitor.  
And whenever I do anything else, check email, input text in a text file, use a different browser, etc., or just not use anything for 15 minutes or so, when I get back to Chrome, and do ANYTHING, try to put in a url, or a search, or a comment, I get the spinning wheel, for at least a minute, to three minutes, until I can do anything!  This is ridiculous...
Re: High CPU Usage - Mac Fiid 1/17/11 1:05 PM
OSX 10.6.5 and Chrome 7.0.517.41

I see chrome peg up to 100% cpu on various sites - generally media-ish sites with lots of flash ads and stuff seem to be worse.

I would suggest a couple of possible features.
1) I want a tool that will show the cpu and memory usage of each tab. (like unix top).  Perhaps even a sub-page tool.
2) I want any tab that isn't in focus either paused or cpu limited until it's in the foreground.  I don't need some advertisement running some badly written animation when I'm not even looking at it.  This might bork some legitimate operations (pandora?), but they could be coded around it, or an exception list could be utilised.

Chrome 8.0.552.237 on Mac OS X 10.6.6 (10J567)

It just started happening recently, and it mostly happens with gmail, which I keep open all the time.  I did just install the "Minimalist for Gmail" extension <https://chrome.google.com/extensions/detail/oddhbkghjoccbljmagcgoklbfdjeiinb>.  I like the functionality, but I can uninstall it if that's the answer.
Re: High CPU Usage - Mac isherman 1/31/11 12:56 PM
@ams16: Please try uninstalling that extension and see if the problem goes away.  If it does, please report this issue to the extension author.
Re: High CPU Usage - Mac ams16 2/2/11 10:57 AM
That did it.  It was the extension.  Oh well.  I liked that extension.

Re: High CPU Usage - Mac dalmz 2/4/11 4:43 AM
1. Google Chrome version number (Tools > About Google Chrome)
Well, there is no menu "Tools" in my google chrome menu bar. The version is: 9.0.597.84.
My Mac OSX version is 10.6.6
CPU: 2.4GHz Intel Core i5, memory 4GB.

2. Steps to reproduce high CPU usage:
I didn't really check the high cpu usage, but when playing flash games and especially Mafia Wars game from facebook, the response in that webpage is very very slow compared to firefox.

Re: High CPU Usage - Mac JDENredden 2/9/11 10:34 PM
With the release of Flash Player 10.2, CPU usage should be lowered. As video now runs through GPU.

So if you still have high CPU must be an extension causing the CPU if so check (http://nerdramblings.tumblr.com/post/3212910011/high-cpu-in-chrome), or Chrome it self, in which you should do a fresh install of the latest STABLE release.
Re: High CPU Usage - Mac leiwei 2/10/11 2:59 AM
Seems that even with the new Flash Player 10.2, Chrome still has intermittent pauses when playing Flash [video], and though the Shockwave Flash Chrome plug-in uses somewhere between 40-60% CPU (according to Activity Monitor), [a YouTube video] is still quite choppy thanks to all the Flash ads from the other opened tabs.
Re: High CPU Usage - Mac MindTooth 2/11/11 3:05 AM
The memory optimization of Chrome is a joke. They should really tweak this and not add features that we don't need.. (cough... Flash)
Re: High CPU Usage - Mac pepijns 2/13/11 3:36 PM
Same here, processors go to 100% when using flash on websites.

1) Chrome 9.0.597.102 beta
2) go to http://www.animationmentor.com/ and watch one of their flash video's, like the student showcase.

Re: High CPU Usage - Mac johnhook 3/2/11 8:26 PM
Workaround and Solution!

In a nutshell: The long and short of it is that many websites today are very resource intensive. The workaround is to share the load among two to four different browsers. This workaround works every time. The browser-builders will have to make the final fixes.

I urge all of you to duplicate my results!

I've been troubleshooting this with Apple for well over 2 weeks and just discovered the root cause and workaround a couple of hours ago. Here's what I sent to Apple:

Subject:
Root Cause Identified for Case 20244XXXX!

Body:
Insufficient Stress Testing and No Load Shedding!

Hello Annette, Jim and Steve,

Please see the attached screenshots.

Engineering, especially test engineering, needs to look at this! When this is resolved Steve can go on stage and show another Safari feature that is superior to Camino, Chrome and Firefox, etc. (I was able to replicate part of this using several boxes at a local Apple Store about a week ago!)

Here’s the deal:

I was blaming Safari because I rarely use other browsers.

1. Open Activity Monitor to All Processes and order by %CPU descending.

2. Launch a browser and go to http://streamingradioguide.com/streaming-radio.php?format=1&radio-format=News/Talk&includeAM=on&includeFM=on&includeHD=&includeLPFM=  
or http://radiotime.com/channel/c_57922/News.aspx, open a few streams and watch the %CPU skyrocket. (I often channel-flip between several streams.)

3. Document the results.

4. Repeat steps 2 and 3 for a second, third and fourth browser.

5. Repeat steps as needed on other test boxes. Repeat everything as needed.

6. Send the documentation of these tests to engineering.

7. Engineering: Replicate results and review all documentation.

8. Make Safari much more resource efficient than any other browser.

Steve can then demo this to the world and everyone will have another insanely great day!

Thanks for another great demo today Steve.

John

Re: High CPU Usage - Mac StevenCee 3/7/11 1:03 PM
Johnhook, I don't understand what the workaround is that you say "works". This sounds like you are telling Apple to use your info to create a better Safari. If I'm missing something, please let me know, as this issue is driving me crazy. I have found that the Beta 11 version of Opera will run a long time with a lot of windows/tabs open, yet not rise above 1.5 GB of RAM, & only after a number of days will it inch up to 2 or so GB, whereas Chrome, Safari, & Firefox jump up to 3 or 4 GB quickly, & I've had them go to over 5 GBs!!!

Activity Monitor reports CPU up to 90% chrome renderer and high google chrome (my CPU fan goes into overdrive)
THEN I close down everything except for one window and the CPU usages stays at the same high number. only when I quit chrome entirely does it go down.
Re: High CPU Usage - Mac TechTard 3/21/11 2:31 PM
This is easily reproducible for me visiting http://www.speedtest.net/ on my macbook, using Chrome 10.0.648.151 beta, running Flash plug-in 10.2.154.25.  Without even running the speedtest applet CPU for Flash plug-in (Chrome) is 45%.  After the applet is run and simply sits there displaying results the usage hovers around 120%.
Re: High CPU Usage - Mac zebr 3/22/11 11:33 AM

CPU time first spiked above 90% when I had tabs open to Hype Machine, Google Reader, and a few blogs from which I had just begun downloading two or three small files. So yes, I was listening to music via Flash. However, Chrome has continued to max out my CPU despite several relaunches (including a few force quits when the browser became wholly unresponsive), and (apparently) regardless of site content-- right now, for instance, the problem persists even though I have only this tab open, and have disabled all extensions.

Getting a lot of Chrome Tab crashes (Snap! error message).

Usually only one browser window, 4-5 tabs, mostly Google Apps products.

Also, overnight, computer processor is using 93-100 by Chrome Renderer.
Re: High CPU Usage - Mac ajoslin103 3/30/11 6:06 AM
10.6.7 Core Duo, Chrome 12.0.712.0 dev

[for me] Chrome seems to spike in cpu usage when it's foreground window has timers and animations running and it's window is increasingly obscured (or pushed offscreen)

I'm working on a simple page with a single repeating timer - no animations, nothing but that timer checking to see if any changes have been made to the form fields.  I mistakenly set that timer low and noticed the problem when bringing my text editor to the front.

-- NOTE: These measurements were made with that single timer running at 1 millisecond interval -- larger intervals with this SINGLE timer didn't show such a large problem, but at any timer interval the results are very steady and reproducible so I report them here.

The more frequent the timer the larger the problem? -- to get these maximum results I set the timer to 1 millisecond -- Chrome did not go above the baseline 20% at any time with any amount/combination of it's window being obscured and the 1 millisecond timer.

   with timer tab open and in foreground    - chrome: 15%    renderer: 20% - baseline
with timer tab open but behind any tab    - chrome: <2%    renderer: <2% - any combination of obscured and offscreen
with timer tab open and in background    - chrome: 15%    renderer: 20%  - unobscured
with timer tab open and in background    - chrome: 25%    renderer: 33%  - < 60% obscured/offscreen
with timer tab open and in background    - chrome: 48%    renderer: 44%  - > 60% obscured/offscreen
Re: High CPU Usage - Mac isherman 3/31/11 3:21 AM

Re: High CPU Usage - Mac MattChrome 4/5/11 7:10 PM
Using latest Dev version of Chrome (12.0.725.0) on my MacBook Pro 2.93ghz C2D, 8gb Ram and latest Adobe Flash installed.

Chrome is using unnecessarily lot of CPU compared to Safari. I just recently switched to Chrome because Safari is a memory hog but now i see Chrome is a CPU hog.

I don't know what's more annoying. A memory hog or a CPU hog and hearing the fans running all day?

I tested extensions and it seems they're not the issue. Also It would be strange if extensions were the cause. That would suck!

Please GOOGLE PUT THIS ON YOUR TOP PRIORITY!: MAKE CHROME LESS OF A CPU HOG PLEASE PLEASE PLEASE!!!!

PLEASE GOOGLE DO YA HEAR ME???!!!!!!
Re: High CPU Usage - Mac MattChrome 4/5/11 7:12 PM
By the way, Chrome IS A CPU HOG NOT JUST WHEN PLAYING FLASH!

Re: High CPU Usage - Mac zefra 4/6/11 5:24 PM
I recently started having this problem too (last few weeks). Suddenly I noticed that my expected battery life on a fully charged MBP 2.4 GHz, 4 GB ram (6 months old) dropped from 6-8 hours to under 2 hours when I had Chrome running. It happens when I am not playing any flash videos etc, just running gmail and some news sites.
It doesn't happen every time I run Chrome, but when it has been open for a while seems to start happening. I have checked the Activity Monitor, and it is always Chrome's fault.

I am now trying to get used to Opera instead (no fan of Safari), but I would really like to be using Chrome as I much prefer it as long as it is not eating up my whole CPU and battery life.

Re: High CPU Usage - Mac llleah 4/12/11 7:18 PM
I'm running Chrome 10.0.648.204 on OS X 10.5.8.

When I open lots of tabs, I get lots of "Google Chrome Renderer" processes in my activity monitor, as I would expect. The thing is, when I close most of my tabs, the processes don't die and my RAM usage doesn't go down. (CPU usage is ok, it's the RAM I really care about.)

My next idea was to kill the extra renderers using Chrome's task manager, but that window only shows processes from open tabs. Chrome's task manager doesn't list a single instance of the renderer, I suppose it has a different name. It would be useful to have a way to figure out which instances of the renderer belong to tabs I have closed so I can kill them manually from Activity Monitor.
Re: High CPU Usage - Mac adk452 4/13/11 10:20 AM
I'm also seeing very high CPU loads with Chrome 10.0.648.204 on OS X 10.6.7, on a MacBook Pro. Just running Chrome with no windows open takes up about 10% cpu between the main process and 16 Worker processes. CPU load shoots up very high when playing a video. The load varies quite quickly, but is often close to 100%, and the video is choppy and even the audio comes out poorly. Load is so high that I have temporarily stopped using Chrome over the past week or two.

Re: High CPU Usage - Mac asdfradii 4/24/11 9:55 PM
running Chrome 10.0.648.205 on imac (os x 10.6.7, 3.6ghz i5, 4gb ram). admittedly, i do have the bad habit of having many tabs opened concurrently but 100% CPU usage w/ a flash plug-in and approximately 2gb ram usage [though a lot of that would be contents from the pages and chrome's individualised tabs] IS a bit farfetched.
this usually occurs, unsurprisingly, after a few videos has been loaded and played. i have tried several suggested solutions (e.g. disabling phishing protection) but to little avail. just now when chrome flash plug-in reached 99-100% consistently and youtube was lagging on chrome (not by internet speed it's loaded quickly, but by both sound and video), i opened the same link in safari and it played perfectly well.
really did enjoy chrome a lot..save for this issue that compels me to bookmark all tabs, quit and restart, reopen, load. it's still a great, clean browser. well okay and the fact that we can neither (or i don't know how to - apologies for ignorance..) choose cache size nor receive a warning before the fateful command+w slips into command+q. do hope this gets fixed soon..

On average 15-20 tabs open, after watching a few flash videos Activity Monitor shows "Shockwave Flash (Chrome Plug-In Host)" at >50% CPU usage, seems to go up the more videos I watch, sometimes reaching >120%. If I kill the process I get the warnings across all tabs but CPU usage hovers around 3% before watching another video.  Cleared cache and updated to the newest version of flash and problem remains.  I'll have to switch back to Firefox 4 now that its out of beta and wait for this problem to be fixed.

Re: High CPU Usage - Mac stebbiv 5/6/11 10:13 AM
Chrome 11.0.696.57, OS X 10.6.7, MacBook Intel Core Duo 1,83 GHz.

CPU usage goes nuts after opening a new tab and entering a query into the address bar (140-180%). Accodring to Chrome Task Manager, most of the CPU usage is by the browser itself.
This happened after last update and I'm being forced to switch browsers very soon.

Same as Stebbiv -

High CPU starts typically after I've entered a search query straight into the address bar. It typically doesn't matter whether I've had a lot of tabs opened or not. The CPU just kicks in and starts up the fan as well.

This has suddenly started being an issue - I am debating more memory or different browser (again) and I really like Chrome :-(
Currently I have 1 window of Chrome with 11 tabs - however issues can arise with less.
Chrome is using 150mb ram  and 11% CPU - main process
9 Processes of Chrome Renderer's
5 Processes of Chrome Workers

This seems like a beast! Please fix.
Re: High CPU Usage - Mac AdamWH 5/12/11 3:01 AM
This is also happening to me. CPU usage of anywhere between 20%-90% while watching flash videos. Macbook body becomes extremely hot and fans kick in after around 2-4 minutes of watching videos.

Steps to reproduce:
---------------------------------------

1. Visit any website that uses Flash, such as Youtube.
2. Play a video.
3. Watch Shockwave Flash (Chrome Plug-in Host) CPU usage climb.

This happens to me too. Most afternoons around 3 or 4PM EST, Google Chrome Helper starts up and eats up 100% CPU.

I usually have around 10-15 tabs open at a time, and it seems to only happen only in the afternoon at the time I mentioned, even though I typically start using Chrome around 9 AM.

Re: High CPU Usage - Mac mediagraphics 5/22/11 12:34 AM
Open your Eyes people! Google Chrome or Google is no different from Microsoft! Google Chrome sabotaging Flash player so all of you will complain against adobe flash performance.... And this is what Google wanted. Try to download Firefox, Opera, Safari or Even IE... It never hang or CPU usage is below 20%! Why? bec.

This is the truth! about Google Chrome... i was an Avid fan of Chrome but after i realized what they are capable i switch again to firefox.

Started Chrome, tried to go to Facebook, then opened new tab to view a YouTube video. Neither Facebook nor video were retrieved, Chrome pushed CPU straight into near 100% CPU.

Happened what seemed like 3 min after starting Chrome - new record, usually runs for at least 1 hour or so before it goes into overdrive. Sometimes doesn't go into overdrive at all.

Had to force quit Chrome, seems to be only way to stop excess CPU usage.
Re: High CPU Usage - Mac NeilWL 5/25/11 7:30 PM
@mediagraphics; Not sure if it is a conspiracy. Maybe more like architecture (is that the word?) Firefox used to do the same as Chrome on my Mac (ie pushed my CPU into overdrive). One of the reasons I went to Chrome (which was stable until now).

Then I turned off hardware acceleration (as suggested by Mozilla) in Advanced Settings and it seems to be running much better. No issue with flash.

Re: High CPU Usage - Mac Carlos Torres 5/27/11 10:41 AM
Same problem. More than 100% CPU usage, how can it be?
It occurs when open a new tab and do a Google search on location bar.
Chrome does not search in Google and starts consuming the CPU.
From there, Chrome does nothing anymore. Stops.

I'm not sure of the exact steps, but every time I look in activity monitor Google Chrome is at the top of CPU usage, and its also got like 20 processes called "google chrome renderer" which take up a fair amount themselves.

it takes 190% CPU randomly, unrelated to the web content. It happened twice when I just start it (only tab window, no webs are even loaded)

annoying.
Re: High CPU Usage - Mac maximiliany. 5/31/11 11:15 PM

Chrome main process uses about 150% of CPU and then get stucked. I've no idea the reason of this issue and got any answer anywhere over the web. I love Chrome but i'm really thinking about moving to FF.

This problems Sucks!!!

It doesn't matter what site I open, Chrome is hogging the CPU with several Google Chrome Worker / Renderer processes.

The problem might started to appear when I installed Adobe CS 5.5.

Too bad, I really liked Chrome.
Re: High CPU Usage - Mac maximiliany. 6/13/11 6:42 AM
Can I at least see some respond that google is handling this, at all?

Why I enjoy google's services, when there are problems google is NEVER reachable, just like we are here talking to air right now, seeing no hope.

Chrome 12.0.742.100.
MacBook, 2.4Ghz intel core 2 duo, OS X 10.6.7

Upon opening ANY website, with only one window and one tab, the renderer immediately goes to 100% CPU usage or beyond. Chrome has become absolutely unusable. All browsing data cleared, nothing else running. This problem sprung up one day out of nowhere and had made me very sad :(
Re: High CPU Usage - Mac rustyD 6/22/11 3:51 PM
Chrome 12.0.742.100
OS X 10.6.7

Works fine for a while then starts heating up my Macbook 2007, fans whirring and pages start to load very slowly. Try to quit and it refuses to quit until forced. I currently have 7 Google Chrome Renderers in Activity Montior using nearly 1.1gb of real memory. Add to that 10 Google Chrome Workers using about 250mb

Machine is only currently running Chrome.

Gonna have to use another browser if this isn't resolved soon. I like Chrome.

Re: High CPU Usage - Mac daemonsy 6/30/11 2:26 AM
I have this problem as well, weird thing was, Chrome isn't even running. This normally happens with my computer when I sleep/wake a few times without shutting down while Chrome is running processes.

Re: High CPU Usage - Mac berhin 7/4/11 7:05 AM
My fan speed spikes from 2000 RPM to 4500+RPM in a matter of a minute or two when I start watching flash videos. I initially thought it was a Chrome issue, but it happens with Firefox as well.  In any case, I installed Shockwave Flash 10.3 r181 and disabled the older Shockwave Flash 10.1 r102. The problem is still there, but it feels less severe now.

Re: High CPU Usage - Mac Mariano Amartino 7/9/11 5:17 PM
Hi there,
sorry to bother you but after reading a lot of pages.... is there a problem or should i switch back to firefox?

Yes, I cant believe there is no solution to this thread and my Macbook Air late 2010 (running OS X 10.7 GM for devs, and Chrome 12.0.742.112) keeps my fan running loud all the time... should i blame Adobe, Apple or Chrome? :)
thanks in advance
Re: High CPU Usage - Mac Fudencio 7/11/11 5:28 AM
1. Google Chrome version number (Tools > About Google Chrome)
12.0.742.112
2. Steps to reproduce high CPU usage
Start the application     X-(

I just have to start the application, what is the problem ? Extremely annoying this issue, back to Safari.
Re: High CPU Usage - Mac snyderguy 7/11/11 6:11 AM
Seriously, guys. I've been staying away from Chrome on my MacBook Pro 13 2.66, but have dared to try to start using it again because I miss it so much. Well, all I've got open in it are a dozen job sites. I didn't use it but to click around a couple tabs and renew a couple searches, then went to Firefox to mess around a while. Then I realized that my fan was spinning like nuts and the thing was getting hot.

I immediately went and quit Chrome (which hasn't had the Flash plugin for months). Two minutes later, all is quiet, the fan has spun down.

Seriously, what the hell is going on and when are you going to fix it?

Entered in Firefox.
Re: High CPU Usage - Mac 3duardo 7/12/11 8:47 PM

Re: High CPU Usage - Mac empimp 7/18/11 1:21 PM
For a long time the common denominator, for both excessive CPU and memory, was Flash.  Several months ago I learned that you can go to about:plugins and disable (or enable on occasion) the integrated "Flash 2" plug-in, which, until yesterday, solved my CPU problem.  

Yesterday I opened up my Chrome, with all the windows and tabs that had previously been open, and instead of less than 20% total CPU usage (I'm a window and tab hog, and <20% CPU isn't bad for me) I was well over 100% between two processors.  At the time I was using the beta version (don't have the full version number, but whatever the most up-to-date 13 beta version was).  After closing most of my windows, restarting both the browser, and my computer, with cache clean-up in between every other step, Chrome was still running the CPU too hard.  After all that I downgraded to the latest stable version (12.0.742.122) but am still having excessive CPU usage.  

The fact that a Google employee asked this back in March '10 and it's now July '11 and, based on all the recent posts, it is clearly a common problem, I have to wonder just how seriously Google takes their Mac users?

With my system about to overheat, I bid adieu to chrome.
Re: High CPU Usage - Mac StevenCee 7/18/11 1:33 PM
I'm a bit amazed as well. This is an issue that has been ongoing for far too long. I try using each newly updated version, but they are all huge energy/memory hogs, so Chrome sits unused, awaiting a version that actually works. I now am able to have literally 200 tabs open using Safari, without it using near the amount of CPU usage as say 20 open with Chrome....
Re: High CPU Usage - Mac Zircon5 7/19/11 5:23 PM
Chrome version 14.0.825.0 dev, OS X 10.6.7, Viewing videos on Justin.tv  Process 'Google Chrome Renderer' at around 80%.  Pausing the video immediately drops the percentage.
Re: High CPU Usage - Mac maximiliany. 7/19/11 10:18 PM
BTW, why is this thread listed "Answered"?
The problem is obviously still exist in vast.

Recently I update from os 10.5 to 10.6.7, the very same issue still exist.

Can I see at least someone say "we are working on it"? I don't feel I am being helpful by shouting to the air.

I have posted the detail in previous posts.
Re: High CPU Usage - Mac cybergabi 7/21/11 2:40 AM
Google Chrome Renderer process just took  up more than 100% of my CPU. I couldn't even save my blog post anymore. It was only one window which was open, but the CPU usage was outrageous. I had to copy my edits, paste them into Text Edit (which together took almost half a minute), and then close the browser and start over again. Never happened with any other browser before.

Is there anything we can do about this? I'm on a 2GHz MacBook Pro, OS X 10.6.8, using Chrome 12.0.742.122.
Re: High CPU Usage - Mac tjolle 7/21/11 5:40 AM
Just echoing, what I'm guessing, is pretty much the consensus of the thread: flash constantly causes CPU spikes. I'm currently running 12.0.742.122 on OS X 10.6.8 (on Macbook Pro) and I've not been using any plug-ins except Adblock Plus. I've tried disabling that and the problems still persist though the CPU usage of Flash seems to be slightly lower.. However, running Incognito-mode seems to more or less fix the heat issue while more evenly distributing CPU usage across the tab and the Flash plug-in. Trying beta version 13.0.782.99 seems to work a bit better but Safari still runs the same videos without causing the fans to turn on. Until this problem gets fixed I'm not using Chrome anymore.
Re: High CPU Usage - Mac maximiliany. 7/21/11 6:27 AM
Flash run HOT on mac on ANY browser. Therefore Steve Jobs is so eager to push flash off the market and replace it with html5
Re: High CPU Usage - Mac cintra 7/25/11 3:42 AM
Does anyone have any idea yet what is causing the high CPU% on Macbook AIR (early version) ?

Never thought I would start using Safari, but now I do, and it works well.. howver I really do want to use Chrome again!

I use the latest Chrome Dev version on all my Macs
I have upgraded the MBA to Lion
Re: High CPU Usage - Mac ThatPythonGuy 7/28/11 11:22 PM
Chrome version: 12.0.742.122
OS X version: 10.6.8

When I open Chrome and visit *any* site, I get the message "Waiting for Cache" in the status bar (bottom) and Chrome gets "stuck"!! The CPU usage increases dramatically.

Solution:
Start Chrome but make sure that no address is requested (so you don't get the "Waiting for Cache" message).
Go to Chrome-> Preferences -> Under the Hood -> Clear Browsing Data -> Choose "From the beginning of time" and "Empty the cache" -> Clear Browsing Data

You will get a progress circle then it will stop. You can then visit any web site and the "Waiting for Cache" message should go!
Re: High CPU Usage - Mac bmenot 8/2/11 10:39 AM
Seeing the same problem as everyone above. Currently running:

Chrome 13.0.782.107 beta
OS X 10.6.8

Chrome is my primary browser, and I am a power user (20-30 tabs). I am currently not on any (that I can tell) Flash-intensive sites, but both the cores on my laptop's Intel Core 2 Duo are > 80%. The Activity Monitor reports that Shockwave Flash (Chrome Plug-in Host) is using 98% CPU and 800MB Real Memory (1.7G Virtual, 50MB Shared, 840MB Private).

Re: High CPU Usage - Mac Firehawk95 8/4/11 7:30 AM
First time visiting this thread... I've been noticing a lot of horsepower being sucked up by Google Chrome in Activity Monitor for various processes.  I thought Camino was bad @ 20% of CPU capacity, but it takes only one chunk.  Chrome takes a lot more for very few open tabs especially when I total the numerous Google Chrome Renderer processes.  Meanwhile, Firefox takes minimal resources; perhaps 5% at most times.  I use Chrome sparingly, and will continue to do so until the geniuses at Google fix it.  It's not like they don't have the resources.

Hey,

Google Chrome 13.0.782.112
Mac OS X 10.6.8
mbp 2010, 2,4 GHz, 8gb RAM

Steps to reproduce high CPU usage:

When I open a couple of new tabs(3+,lots of flash) my cpu usage goes to 100%. The google renderer processes use about 80% of the cpu. And the Shockwave Flash process sometimes takes up 100& cpu usage.
Re: High CPU Usage - Mac JYHASH 8/17/11 4:44 PM
This is still an issue for folks, and I'm at a loss as to why.

Google Chrome 13.0.782.113
Mac OS X 10.7
MBP (17-inch, Mid 2010), 2.66 GHz Intel Core i7, 8GB 1067 MHz DDR3 RAM

Steps to reproduce high CPU usage:

Happens on virtually any Flash heavy site. Activity monitor starts to top out at 90%-100%, video and game stutter, and performance of computer itself begins to tank, even with the 8GB RAM and fast CPU cores.

I used to recommend Chrome to my fellow Mac users, but I can't really do that anymore because of this issue. I originally switched to Chrome because of the issue of Flash Videos stalling constantly in Firefox, but Chrome has the same problem for whatever reason. I've cleared the caches, I've tried running with no tabs open but one, and on something as generic and friendly as YouTube, and it still stutters out every 3-5 minutes or so. Please fix it, and I'll come back, but I'm off to find another browser for now.

When I try to open a website in Google Chrome, it immeadiately takes between 99 and 100.6 % of CPU usage. The content of the website (flash or non-flash) does not seem to matter. I tested it with Gmail and Reddit, among other websites. Naturally my computer becomes extremely slow. The website I try to open does not show up. With Gmail, sometimes the "This seems to be taking longer than usual" screen appears. I disabled all installed extensions but it did not help.

Re: High CPU Usage - Mac jpbianchi 8/21/11 8:31 PM
I updated Chrome to last version yesterday, but same problem.  After a while, chrome renderer just eats up 99% of cpu time for just opening 1 more tab or 2, although there is only one tab.  Trying to scroll in that tat while the other two are downloading just crashes chrome ... talk about independant processes ....
I removed all my extensions, it seemed to work normally, and then I restarted them one by one, and chrome seemed to remain fine, but, after a while, same problem again.
4 months ago, I used to be able to run 40 open tabs with no speed problem whatsoever, life was great, and now, chrome just sucks.  I started Firefox and it's a blaze, so Chrome is the issue.  I don't know what they changed a few months ago, but they should figure out since it seems I am not the only one in that case.  
When rendered is not eating all the cpu resources, Chrome remains slow nonetheless, it takes 2 seconds to open the bookmark manager, bookmarking shortcuts sometimes don't even work etc It's like Chrome is DELAYING 'things' even when it's not using resources because when I open it after Firefox, with only one tab, Firefox becomes very slow too.

Does anyone know a FINE monitoring tool, more accurate than activity monitor, so I can track which process, which subroutine is delaying everything?

thanks a lot
Re: High CPU Usage - Mac jpbianchi 8/21/11 9:19 PM
OK, I have FOUND SOMETHING.  I opened the Chrome task manager (Tool icon / open background pages (should be called 'monitor' instead of open in my opinion...), and then I clicked on 3-4 links in a row from a page, Chrome renderer spikes to 90% while the pages don't seem to load at all, BUT I noticed that it is spending all its time on the process of the page where I clicked those links, although that page was finished downloading.

What it is doing there I have no idea.  I tried to kill that page before the pages finish downloading to see if Chrome would switch its attention back to where it belongs, downloading the new pages but NOOOO, it just takes ANOTHER TAB with an already downloaded page, and runs it at 90%.  It does that on and on every time you kill the cpu eating process, even with 'stupid' pages with almost no content.

In short, you open new pages and Chrome spends all its time on an already downloaded page ... This can't be a font, memory, or anything else problem, it comes straight from the subroutine that decides which page to spend time on.  And it's been there for many many upgrades since I've been having this problem for months.  I just can't believe Google developers don't see it.  

That is clearly a BIG BUG TO FIX from Google.
Re: High CPU Usage - Mac jpbianchi 8/21/11 9:22 PM
And it's even WORSE than that actually because, if I kill the 4 new pages, and click on the links again to re-download them ... guess what?
It does exactly the same thing, it spends all its time doing nothing on the 'origin' page, and does not even go in the cache to pick up those last pages...

Again, a BIG BUG in Chrome's task priorities management or stgh like that.
Re: High CPU Usage - Mac jpbianchi 8/21/11 9:24 PM

Re: High CPU Usage - Mac earthcub 8/26/11 12:42 PM
I don't think this is a Chrome issue as much as it is a Shockwave problem because I have the same problem in Firefox.  Anytime a Shockwave process is started in either browser, it spins wildly out of control until the CPU usage is radically above normal, my laptop fan responds accordingly, and I'm forced to shut down the plugin.

My wish is that Google would use their power to get Adobe to fix their software because the average human just gets ignored.

I've just killed "Google Chrome Helper" on my MacBook Pro 13'' Early 2011 Machine running MacOS X 10.6.8.
Google Chrome Helper was listed with a usage of 99,8% of the CPU, causing my fan to run over 4k rmp and heating up my mac up to 90° Celsius.

This was not the first time... :-(

Now my MBP is stock-still and I can finally concentrate on my work.
Re: High CPU Usage - Mac davidje13 9/6/11 4:32 AM
My installation used to be fine, but I started noticing random fan speed-ups recently (past few weeks) which would only go away when closing chrome. I just checked activity monitor and saw Google Chrome Helper using over 100% cpu, which led me to this thread. Chrome is at version 13.0.782.218 (not the most recent, apparently).

It usually happens when my RAM is pretty full (my poor 4-year-old mac only has 1GB), which may explain why it's only happened to me recently - I usually don't let the ram fill up, but I've been using a lot of ram-intensive programs lately.

The problem is *not* related to flash, that is a different and totally unrelated problem. I have all plugins disabled by default, and rarely ever enable them.

That's all the relevant stuff. From here on it's just ramblings that might be useful:

It is pretty sporadic for me, happening maybe once or twice each day. It can happen when there are only 2 or 3 tabs open (just now it happened with 2; the iGoogle homepage and a BBC news article). I don't know if it helps but to give more background; I have a few greasemonkey extensions (checked them, no infinite loops or any funny business), google's RSS subscription extension, and the send from gmail extension. A couple of the greasemonkey scripts are newly installed, but they just glue stylesheets onto some pages (including iGoogle).

Killing Google Chrome Helper fixes the issue, and chrome seems to stay stable (no crashed or frozen tabs). I'll try to diagnose it a bit more next time it happens.

Possibly unrelated, but about that time I also noticed that chrome had put itself (or something else put it) into the automatic startup list, though this could have happened long before (I've since removed it and the problem persists).

This is ridiculous!

I have a late 2008, Macbook Pro and I have google chrome as my default browser. I have had no issues with it so far, but now I'm just getting annoyed. I have to constantly check my shockwave flash plugin, because it likes to "run away" with my CPU usage. I'll be on an all text page, like fanfiction.net, and it'll have 25% of my CPU gone! ON A TEXT BASED SITE. Thats ridiculous!

Since my macbook pro is a bugged model with a screen flicker issue on the 9400 graphics card, I am forced to use the 9600 card which makes my computer run hotter. Shockwave taking all that CPU just makes it run even HOTTER then normal for that card. This issue is going to run my poor little Mac ragged.

Chrome used to work great for me, much faster and smoother than new Firefox, but it recently started to freeze on me when opening new tabs with flash content. Whole Chrome seems to block until the new tabs are fully loaded and than continues to work normally..  also, I've noticed that no content gets rendered in any new tab (it's just blank white, even on pure html pages) until all open tabs finish loading... once loading is finished Chrome seems to unfreeze, although CPU (and memory) usage are still very high, and scrolling is sometimes a bit jumpy.

Re: High CPU Usage - Mac davidje13 9/19/11 8:58 AM
more testing and I can say this happens exclusively when the ram is full. It's happened when chrome has been in the background (running only the igoogle homepage with very simple widgets) and another process has filled the ram (xcode gathering iphone device information, in this case). It *never* seems to happen because of a direct action within chrome (loading a page, opening a tab, etc.) so I'm inclined to believe this is something to do with the memory moving from ram to swap file (or whatever the mac equivalent is).

I attempted to get more detailed information, but chrome's task manager doesn't list the process (believes chrome is using ~0% cpu). I'll see if I can find a minimum working example, but it tends to happen only after chrome's been open for a few hours, and possibly only if the mac has slept at some point while chrome was open.
Re: High CPU Usage - Mac davidje13 9/19/11 9:00 AM
also I think I should point out to some of the other posters again that this issue is entirely unrelated to flash and shockwave. That is an unrelated issue.

I am not sure how to reproduce it. Recently it just constantly uses CPU. around 80 or 90 percent even more. I started to close tabs one by one hoping to find the one with worst CPU usage nothing changed.

Google chrome renderer is the one that uses the most CPU time.
Re: High CPU Usage - Mac photondrm 10/27/11 4:29 PM
Apple only allows Safari browser to grab hardware acceleration for Flash content, that's why your CPU's are going nuts and your computer is overheating and your two fans are screaming along at about 6,000 rpm's instead of 1,995 rpm's. Turn on your Activity Monitor and run the same page with video playing and in the Activity Monitor Window you can watch Safari use about 12% to 14% CPU and then turn Safari off and turn on any other browser (same page), and you see them grab about 100% of CPU and Flash Plug in. Until Adobe Flash Player can grab hardware acceleration I'd say use Safari to look at any page with Flash content, particularly if it has video since video uses maximum CPU calculating functions.  Hope this helps you guys.

I upgraded to dev because I was hoping it would fix the problem.  Chrome eats up 100% of my cpu and just locks up.  I don't think this is the flash problem because in the Chrome Task Manager the Browser is what is at 100% and not the flash extension.  I can't figure out how to reproduce because it seems to happen the majority of the time.

I'm actually posting this from Safari because it is so bad.  I want to move back to Chrome but until you figure out what is going on I'm just going to have to use another browser.

I wonder why this issue is listed as "ANSWERED" in the list of posts, as it's certainly far from "answered", much less fixed! This is absurd, I just opened Chrome (OS 10.6.8), and it's using MULTIPLE GIGS OF RAM, there's the listing of Chrome, then 40 or more listings of "GOOGLE CHROME RENDERER" each with 40 to 100MBs of RAM being used! This is ridiculous, it's taking  about THREE GIGS of RAM.....

I backed off using Chrome for a couple months, hoping against hope Google has fixed this issue, but I can see it's back to Safari again....

2. If I close my iGoogle page Google Renderer CPU usage went from 300+MB to 80MB.  Opening iGoogle doesn't make the CPU usage to go up right away, it slowly creeps up to this usage.
Re: High CPU Usage - Mac Designade 11/14/11 1:17 PM
Update to my reply- re-opening iGoogle and Reader just creates another line on my Activity monitor, which jumps to almost 100MB for each line, so back to the full 300MB's
Re: High CPU Usage - Mac StevenCee 11/14/11 2:37 PM
I just tried opening Chrome again today, after downloading the newest update, and newest flash, etc... Well, it soon rose to 3 or 4GBs! I had a good number of tabs/windows open, but nothing that was playing flash stuff, etc.  All those lines of "Renderer" & their attendant batches of memory that show up in the Activity Monitor are ridiculous!  How absurd to have memory usage run up so high so quickly, or at all for that matter!

Mac v15.0.874.121

Chrome works browsing various websites for a few minutes then locks up and cpu goes to 100%.  I have to force quit to free the CPU back up.  I have deleted and reinstalled and it still has the same issue.  I tried disabling all plugins, no luck there either.  I have tried rebooting, no luck.  This started a few days ago.  Other browsers are working fine.  Running Lion 10.7.2.

I could post crash report but its quite massive.
Re: High CPU Usage - Mac SCCThree 11/19/11 3:48 PM
Thought it was my outdated version of flash.  Just updated and it still locks up after a couple minutes.  At the bottom it says 'Waiting for cache'.  The browser isnt locked up you can scroll around but CPU is pegged and navigation stops working.

2.  It seems when opening more than two or three tabs, Renderer takes close to 100% of the CPU, according to the activity monitor. If I shut down the task and refresh those tabs, things appear to be good again, at least for a while.  Not sure, but I've added a number of extensions lately and one of those may be misbehaving.

Re: High CPU Usage - Mac barrylovelace 11/25/11 6:09 PM
A FIX!

Can't believe this worked! To watch flash videos (YouTube etc) on your MAC without the fan sounding like it was going to fly out of it use Safari, BUT you have to go to the following link and uninstall Shockwave as you don't need it to watch these videos. My CPU did not go up nearly as high and you can barely hear the fan running as when watching same videos in Firefox or Chrome.

NOTE: The 'installer' option for Mac OS has the Unistall in it as well.
Link Here: http://www.adobe.com/shockwave/download/alternates/

Hope this helps the peeps who are/were frustrated, as I was, when trying to watch flash videos in Chrome or Firefox.

Enjoy your vids! :)

PS - I will feel like a fool if this is already here somewhere, but I didn't notice it ;)

I'll be browsing for awhile, then one of the helpers go to 100% (1 core)

Then I'll keep working away, and it jumps to 200% usage (2 cores), then awhile later 3 cores... then I have to kill it to get it back to normal. The timeing on it seems to be about 1-2 hours between cpu jumps.
Re: High CPU Usage - Mac Zethos 11/27/11 5:22 PM
Whats also interesting is if I kill the run away process chrome reports one of my extensions crashed (in this case it was 1password) but previously it was adblock, and clicktoflash. So it's not always the same extension that goes nuts. It appears to be something with the extension system.

Re: High CPU Usage - Mac stevenroose 12/9/11 3:57 AM
I have Mac with Chrome 16.0.912.41 beta. MacBook Pro i5 2.66GHz 4GB RAM.
I have around 20-30 tabs open usually. When flash is busy doing something (Google Music, Youtube, Google Talk, ...) and I open a new tab, CPU peaks 200% for like 5 seconds, then the tab opens. When I type something and hit enter, another peak to 200% for like 7 or more seconds and then the tab opens real slowly.
I think my Google+ tab has something to do with it too, though. And Gmail. I always have Gmail and Google+ open. When I close those, Chrome usually runs a huge lot smoother!
Re: High CPU Usage - Mac stevenroose 12/9/11 3:59 AM
ALSO, VERY IMPORTANT:
Google's own RSS Subscription Extension seems broken. When I click the RSS button in the OnmiBox, 2 threads for the extension open (Task Manager) and take like 60% of my CPU together, slowing down Chrome extremely hard.
Only way to get Chrome back up working is to Force Close the both threads.

SHOULD BE FIXED!
Re: High CPU Usage - Mac jfeighery 12/18/11 6:42 AM
Okay, Chrome.. I give up. I originally switched to Chrome because Firefox was hogging my RAM, but this is much worse. I guess I'll try going back to Safari until you fix this. At least Safari has Flash blocking extensions that work. Click to play doesn't seem to work at all in Chrome.
Re: High CPU Usage - Mac Susurrus 1/2/12 2:20 PM
16.0.912.63 on OS X 10.6.8

According to the Activity Monitor it is the 'Shockwave Flash (Plugin-Host for Chrome)' which causes high CPU usage. Most of the time it consumes 5-10% of the CPU and then all of a sudden, it jumps to 90+%. Sometimes it is a video, sometimes a game and sometimes simply entering a webpage such as guloggratis.dk which causes the CPU usage to jump through the roof.
Re: High CPU Usage - Mac Webfox64 1/3/12 2:22 AM
Uninstalling Flash Player (Adobe) resolved this for my MAC but I like Flash Player and thats why I stop using Chrome as long as this bug is not fixed. ByeBye Chrome.

Re: High CPU Usage - Mac kinuhlp 1/5/12 12:05 PM
I am on a Mac and new to Google Chrome after using Safari and Firefox. I heard good things about Chrome and thought I would try it. Chrome consumes most of my CPU, even with a single tab open and nothing else running! If I go to YouTube or try to play a video of any sort, it completely freezes! This issue seems to date all the way back to 2008 from what I can tell. Google, what are you doing? :/
Re: High CPU Usage - Mac egyptlang 1/10/12 8:47 PM

2. Going to www.gaiaonline. The ads are causing my CPU to spike up to abnormal levels. Usually it doesn't cause a huge CPU spike, but now flash player is eating up 60% of my CPU.

Google, what on earth are you doing? FIX THIS PLEASE.

on a side note: It only spikes with certain ads it seems. But it's still a problem!
Re: High CPU Usage - Mac pasherman 1/11/12 12:53 AM

Re: High CPU Usage - Mac I Saw The Sky 1/17/12 4:56 PM
Like egyptlang, I also have noticed extremely high CPU usage while visiting gaiaonline
Google Chrome (16.0.912.75) on Mac OS X (10.7.2)
It will spike to 100% CPU usage for one tab, sometimes multiple tabs will spike.
I have Adblock, the Chrome ad-trace opt-out, and firebug (disabled) as my only extensions.
I don't see any connection with flash and the spikes, sometimes it will spike on really light-content pages on gaiaonline.

During the high cpu usage, Chrome becomes unresponsive for 5-10 seconds (not beachballing, it seems just frozen for a bit)

Not sure if this is a chrome issue, or if gaiaonline is doing something weird.
Re: High CPU Usage - Mac danemerewell 1/20/12 4:29 PM
It is completely and utterly ridiculous that an internet browser consumes around 500mb of active memory with 6 tabs open. Opening a new tab brings everything to a complete standstill. It gets so bad other applications completely stop functioning (Mail, Spotify).

Re: High CPU Usage - Mac wolfson109 1/25/12 5:33 AM
I'm running Mac OS 10.5.8. I checked Activity monitor and it was telling me that it was the Shockwave flash player that was using all my CPU (100%). FIrst off, I force quitted Shockwave, then I went to about:plugins in the Chrome browser and disabled flash. Chrome comes with html 5 support anyway so you don't need flash for most things.
Re: High CPU Usage - Mac egyptlang 2/4/12 7:34 PM
I get a CPU spike when refreshing a page, or when opening a new page. It spikes up to over 20%. Is it supposed to be doing that? And on some occasions, it spikes past 50%!!! I REALLY don't think that my browser should be causing that big of a CPU spike. The only extension I have added is Add Block Plus, and it barely takes any CPU. But without the Ad Block Plus, sites like Gaia Online practically blow up my CPU. FIX THIS PLEASE. I DON'T WANT MY LAPTOP TO OVERHEAT.
Re: High CPU Usage - Mac techdudester 2/6/12 2:30 PM

Re: High CPU Usage - Mac h34v3ns3nt 2/7/12 4:22 AM
Anyone using Macbooks, think about upgrading your Hard Disk. The 5400rpm drive is waay to slow, even a 7200rpm drive only just cuts it. I get very frequent machine lock ups due to disk activity.

Install MenuMeters to see what your mac is doing
http://www.ragingmenace.com/software/menumeters/

Also Listening/Watching the disk activity will give insights into exactly whats going on and when
http://fernlightning.com/doku.php?id=software:fseventer:start

However, I also get 100% cpu pegging when opening new tabs and put this down to chrome extensions and active 'pinned tabs'. 3rd party browser extensions and their problems are very hard to contain and fix as they are out of the remit of Google's code base.

Its very easy to point fingers, but none of you are actually investigating the root cause. Just bitching.
IMHO, Chrome is simply the finest browser to date.
Re: High CPU Usage - Mac egyptlang 2/7/12 5:35 PM
@h34v3ns3nt

No doubt that Chrome is the best browser available, but I'm wondering if the CPU spikes I am experiencing are normal... I mean, they're spiking abnormally high for just refreshing a page. Over 50% at times for just refreshing a single page? I don't think thats normal. And I know that it's Chrome thats making my CPU spike, I was watching it on Activity Monitor.

The fans kick up really fast when i play a flash video embedded in a web page, such as in this one: http://www.gogoanime.com/rahxephon-1-rahxephon-episode-1

my mac is a new 2011 model with great specs and on safari 5.1.3 there is no fan noise when i watched the same exact video. i also experienced this problem in v16. due to the issue i have gone back now to using safari as my default browser, reluctantly since i much prefer chrome and its being open-source and regularly updated, but i dont want to use one browser for my anime and another for other things. i hope this can finally be fixed soon.
Re: High CPU Usage - Mac cfishb 2/15/12 9:07 AM

have very high CPU usage. everything is very sluggish. and non responsive.
Open apps: VLC, Itunes, Utorrent(not activly DL'ing)
Open sites: Gmail, Facebook, Twitter, Eztv, IMDb, Youtube
Finder is at least 6-7 seconds delayed in reacting to clicking the touchpad.
I try and close some of the many Chrome renderer and Chrome helper tabs showing high usage in Activity monitor, but then the sites crash. And the Chrome shockwave plugin uses alot but when i close it it crashes the plug in. (obviously)
I hope this can be resolved. I like Chrome and want to continue using it.

2. Steps to reproduce high CPU usage
The second I open it, it goes to a simple non-flash login for my fileserver and all 6 cores immediately jump up to 100% and it will typically cause my computer to lag for a second or two. Sometimes, it will lock up my computer ( can't even move my mouse ) for a few seconds.

note: running "old_chrome 17.0.963.78" seems to still use alot of cpu in comparison to my other computer ( with the same extensions ) but its significantly lowered. The highest cpu spike with "old_chrome 17.0.963.78" has been around 40% on all cores.

Re: High CPU Usage - Mac xenomojo 6/13/12 5:50 PM
Activity Monitor shows Google Chrome Helper (NOTE: NOT flash plugin) taking almost 100% CPU.  This happens to me every few days or so.  Not sure what I'm doing (if anything) to trigger it, seems to just start spinning on its own.

If I force quit just the Helper process, it will get respawned and all seems well.  Stopping and starting the entire Chrome app works too, of course.

I'm using Mac OS X 10.6.8 and Chrome Version 19.0.1084.54.

Sampling the Helper process makes me suspect that Cloud Print is somehow to blame.  The following is consistent on every sample:

Google Chrome Renderer is usually the top CPU user, sometimes 20-25%.  This causes my Mac's fan to be on high speed most of the time.

I do not know how to reproduce it.  Maybe when I have a lot of tabs open.

When I visit sites with Flash, then the Flash plug-in uses much more CPU.

It is primarily Chrome (and Flash) that causes my Mac's fan to turn on.

Is there a way when looking at Activity Monitor to tell which tabs are causing the high CPU usage?

Hi FrazerKirkman,

No, Activity Monitor does not tell.  When I double-click on a Process Name, such as Google Chrome Renderer or Shockwave Flash (Chrome Plug-In Host), it pops up a window which gives additional information with 3 tabs:  Memory, Statistics, Open Files and Ports.  There's also a "Sample" button which produces a whole bunch of lines of technical data.  None of these tell which tabs is causing the high CPU usage.  Did you want to see what is in these?

Right now, Shockwave Flash (Chrome Plug-In Host) is using the most CPU, at 11.3.  There are about 21 processes of Google Chrome Renderer, which are using between 0.0 to 2.3.  All combined, the CPU usage is not high and the fan is not on.  I think this is probably because I only have one Chrome window open.  I opened another tab and went to a website that has a Ticker Tape running along the bottom, which is powered by Javascript.  Now, one of the Google Chrome Renderer processes has spiked up to 13-15.

However, I've opened a third window and went to CNBC.com, which I thought was a big CPU users, but I cannot seem to drive up CPU usage significantly.  Google Chrome Renderer usage has dropped.  I cannot reproduce the problem.  I'll try to come back and post another comment again when the fan is on.

every time I open google Chrome and try to search or open any page on Chrome. It uses 100% CPU and it takes a while to lower the CPU usage.

was experiencing this on firefox, activity monitor showed shockwave flash plugin at 100%.  right click video and select settings.  Increase local storage from 10k to unlimited.  seemed to solve the problem, but im not sure what is actually being stored.  maybe someone else can answer...

I cleared browsing data (cache) and flash is included in google chrome and says it is up to date.

Chrome version: 26.0.1410.43

High CPU usage occurs within a minute of opening chrome. It is the "google chrome worker" that operates 95% cpu without any videos playing at all, the only browser window open is gmail.

Try this for a fix.. it appears chrome somehow manages to run multiple versions of flash / shockwave at the same time.... this shows how to disable all but the current version....

OSX 10.8.4
Version 29.0.1547.65

The attached shows the number of processes created by Chrome.  At the moment it's low but at times it eats the cpu and memory of the machine especially when Chrome has been open for a while.  I tend to have to restart Chrome which happens every few hours.  When in high usage my mac and Chrome is unusable.   There doesn't seem to be any one particular site that causes it but just a continued hogging of the resources over time.
