I sometimes have a bunch of tabs opened in Google Chrome, which I believe creates a new process per tab. I would like to be able to identify the tab that is using up the CPU.
Is there an easy way to to that?

1You can check which tab uses how much CPU from within Chrome. Click the wrench then in Background processes– Uri HerreraCommented Dec 21, 2011 at 18:45

For MacOS, click on the three dots in the top right of chrome browser  Then click "More Tools" -> "Task Manager" You can then sort by Memory footprint or CPU – stevecCommented Jul 12, 2020 at 3:05

Pressing Shift + Esc on Windows or Linux, will bring up the Chrome Task Manager with a row for each tab - you can sort by Memory, CPU and a couple of other columns.
Alternatively on all OSes, you can find it through: Menu button → Tools → Task Manager.

9By default, Shift + Esc doesn't appear to work, at least on a Mac it didn't. Menu, More Tools, and Task Manager worked a treat. Commented Jun 23, 2015 at 12:25

6There isn't a keyboard shortcut on Chrome OSX but, you can find it under the Window menu next to Download and a Extensions– jb510Commented Jun 27, 2015 at 17:18

3On OSX with chrome 57.0.2987.133 (and it has been like this for a while), it only shows non-zero CPU on the broser table entry, which is of not much help. Commented Apr 25, 2017 at 10:22

Chrome also has a more detailed task manager that can be accessed by right click in the title bar and select "Task Manager" (or Shift-ESC). You can see which tabs or extensions are using the most CPU or the most memory and switch too them.
