How do I identify which process belongs to which tab in Google Chrome?

Normally, I have a (ridiculously) large number of tabs open. If I need to free memory on my box, I would like to choose based on tab/process memory footprint.

I also have run into the same issue and glad there a number of good answers. I usually exit Chrome (Menu -> Exit) and restart. All tabs and windows reopen quick and with fresh process memory. – Brad Patton Feb 27 '13 at 2:24
I used to open windows taskmanager and hover over my chrome tab to see which process would show activity :) Good question, good answers, thanks. – Yoh Feb 27 '13 at 10:13

Chrome has it's own in-built task manager which makes it easy to identify which process belongs to which tab(s). You can access it by the hotkey Shift+Esc or by right clicking on the title bar and selecting "Task Manager".

Chrome also has a more detailed memory page which can be accessed by opening a new tab and entering chrome://memory-redirect/ into the omnibox. It can also be accessed via the "Stats for nerds" link in the Task Manager.

What is the hotkey for the task manager on a Mac? – Kevin Feb 27 '13 at 3:49
@Kevin According to this post there isn't one by default. But this page explains how to set your own.!topic/chrome/xz-9TlEwwCc – Dracs Feb 27 '13 at 3:57
@Kevin: no hotkey, but it’s accessible under the “Window” menu. – PLL Feb 27 '13 at 23:07

In chrome://memory-redirect/, you can see all open processes (tabs, plugins, extensions, etc.), including their private memory usage and their PID.

Using the PID, you can kill the corresponding process from a Command Prompt / Terminal:

  • Windows:

    taskkill /PID <PID>
  • Linux:

    kill <PID>

Using the built-in Chrome task manager is a lot more straight forward. – this.lau_ Feb 27 '13 at 5:46
The shortcut to open the built-in task manager is Shift-Escape. – Riking Feb 27 '13 at 19:32
@Riking - This short cut doesn't show up on my Mac. Best to go Menu > Window > Task Manager – PhD Feb 27 '13 at 20:15
Shortcut no longer works in my Chrome. – Matthew Lock Feb 28 '13 at 4:44

You have to just right click and you will get the Task Manager for Google Chrome

This is a feature given by Chrome so that you can easily see and tab and also you can close the tab and get the detail of the tab

The detail is given below in the form of figure

Nice screenshot. – kevinarpe Feb 27 '13 at 11:24
I always knew it was there, but I had no idea the Chrome Task Manager was so easy to get to. Thanks. – Edward Robertson Feb 27 '13 at 18:26
In Windows 7, right-clicking alone did not bring up the context menu as in your screenshot, it brought up a list of frequently visited and pinned tabs. I had to shift-right click to bring up the version that you show here. – Zack T. Mar 13 '13 at 21:29

In chrome go to the Menu → Tools → Task Manager.

This will bring up a list of all the tabs, background processes, plugins, overall Chrome process, etc...

If you right click in this window you can have it display the OS process ID associated with each tab. This should you allow you to compare that to the process ID in windows task manager, top, or whatever you use to view processes.

Pressing Shift+Esc, you will get the process manager then you can kill the processes, select the desired one (You'll see the title from the website on the tab), and just click "End process", Sort it by private memory (with the arrow pointing down), so you will see the most consuming tabs first..
