How to find which tab a particular Chrome process refers to

Question

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.

Press Shift+Esc to bring up the Chrome 
Task Manager under Windows, or select it from the Window menu under MacOS. It will tell you how much memory and CPU each tab uses, and its process id if you enable the process id column. You can also switch to a tab by double-clicking it, or kill its renderer process.

If there's still a sneaky process that isn't showing in Chrome's Task Manager, you can launch Chrome with the command line switch --task-manager-show-extra-renderers (from the Command Prompt or a shortcut under Windows, or from the Terminal or an Applescript under MacOS), but my current experience (2019-07-13) suggests that this may cause Chrome to sometimes crash, at least under MacOS.

Open the chrome task manager and right click one of the headers (task, memory footprint, etc.). From the list that appears, choose CPU Time.
Now open windows task manager and make sure CPU time is also one of the headers by clicking view -> select columns -> CPU Time -> OK. Now sort by CPU time in both task managers.
Chrome task manager will show you what the tab is, then match the CPU time to the process in windows task manager to close exactly what you want from the windows task manager (if closing it from the chrome task manager is not sufficient for you).
I found that when closing a process from the chrome task manager, it does not always close from windows task manager, so I prefer to use windows. Hope this helps you too.

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.
