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.
