Why do I have multiple instances of chrome.exe? Google Chrome Guide 10/29/08 5:53 PM

Due to it's unique design Google Chrome starts a new process for each tab that is opened. It should make your browsing speedier and safer. For more about Google Chrome's unique architecture, check out the Chromium blog post below.

Safer? Who knows?
Speedier? Just the opposite. With an older PC, I've found the only way to keep the thing moving is by just not adding any extensions.

Well that explains something else.  Chrome starts a new process for each extension that's enabled too.

wtf is wrong with Google? I have 6 tabs, but 17 processes running each taking from 8 MB to 34 MB!!!!

@Ravendon, since you asked, "wtf is wrong", it means you haven't searched the forum. Please do. The answer has been given several times to people who have asked politely.

Chrome doesn't seem to release the copies of itself instantaneously when I close it either. Anyone know why this is the case?

The only relevant result I find when I search the forums is a link back to this page. So it's not really very helpful when vasa1 says "The answer has been given several times to people who have asked politely."

SAME f-ing problem here! just 1 tab opened appears 8 in task manager! eating memory away!

it's called "Multi-process Architecture" and is one of the features of Chrome.
If a web site crashes your browser it only crashes the TAB in which it is loaded.
Each TAB in chrome is a separate process.
This is why you have chrome.exe showing a number of times.

If you right-click the Chrome titlebar you will see it has it's own Task Manager'
Here you can see which pages/processes is doing what, how much memory each is using and hung pages can be closed by choosing 'End Process'

You will also see a 'Stats for nerds' link which will load a page with more memory information about the currently running chrome processes.

To those of you who keep getting impatient when people ask this question, and therefore reiterate that Google Chrome opens a separate instance for each tab, let me be clear with the problem as I see it.  

You've got one tab open, but several instances going.

Alabubba's response is a good one.  The Chrome task manager (a good feature for trouble shooting) shows that when Chrome is open, there is one instance for the browser itself, then one for a tab, then additional instances for plug ins (mine had Browser, this tab, and shockwave).

For fun I tried a very unscientific experiment: I opened Firefox and IE.  And then opened the same three tabs.  Once everything finished loading, here is the memory usage (approximate):
Chrome: 240M
Firefox: 175 megs plus 25M from the "plugin container" which opened when Firefox did=200M.
IE: 220M
Close all but one tab on each:
Chrome: 130M
Firefox: 127M+22M in Plugin Container= 149M.
IE:  at first, all four instances continued with a 156M memory usage.  When two closed, it was about 70M
(the problem I always find with IE is it is so slow, which this little test shows--loading and closing slowly).

This is of course a simplistic test, since there are other things going on underneath that I don't understand.

Seems each has its value, depending upon what you're looking for.
