I often have 6 or 7 separate Chrome windows open, often with 5-10 tabs in each. When I look at Windows Task Manager, I see each chrome.exe process, with some using a large amount of memory. How can I find which particular tab the process refers to? I want to know which one uses the most memory and close that tab instead of having to close every Chrome window. Is there any way to get this information? This is on Windows Vista, but it is the same on other versions of Windows as well.

(6 or 7) * (5 to 10) = (30 to 70) Why in Torvalds' name do you have so many tabs open at one time?!? – Puddingfox Apr 23 '10 at 2:39

Press Shift+Esc to bring up the Chrome Task Manager. It will tell you how much memory each tab uses, and its process id if you enable the process id column. (and also let you close tabs if you want)

Use the Shift+ Esc shortcut key to bring up the Task Manager,

or go to the wrench icon and go to Tools -> Task Manager.

You'll be able to see the CPU usage of every tab and plugin as well as memory usage.

Chrome should have a separate process for each tab. Find the Chrome process that is using up the most CPU porwer (using task manager) and kill it.

There is usually a master process, and that one often takes up the most CPU. If you kill that process, you risk killing the entire browser. Better to just use the built-in task manager, which shows stats for each tab. – nhinkle♦ Oct 10 '11 at 5:48
And, in addition to what nhinkle said: Chrome does not necessarily have a separate process per tab. That's just one of the options. There are others, and you've no idea how the questioner has xyr Chrome configured in this regard, since xe hasn't provided that information. – JdeBP Oct 10 '11 at 10:04
So when I looked at the Task Manager, there was just a single Shockwave Flash process that was taking up the whole CPU, but I can't tell through which tab it is running. – Uri Laserson Oct 10 '11 at 16:09
What part of Chrome does not necessarily have a separate process per tab. is so unclear to you that you persist in looking for a single tab to be associated with this process? End the process and you'll discover, from an unslaught of little sad pictures, the harsh truth that your Shockwave Flash process is doing all of the Flash plug-in work for every tab that has Flash on it. – JdeBP Oct 11 '11 at 14:38
