Reduce Google Chrome CPU Usage

Google Chrome uses a multi-process architecture which means all running applications in Chrome are isolated from each other. Due to this, we have better control over tabs, plug-ins, and extensions which imply, when a plug-in or a tab crashes, we have our other tabs and processes undisturbed.Google Chrome sometimes takes a significant chunk of CPU usage because of this multi-threading process. Let us see some tips how to decrease Google Chrome CPU usage.

Review and sweep-out unused extensions.

We may have some extensions in our Google Chrome that installed by third-party applications like antivirus or firewall which are hardly useful. So just click the wrench icon > tools > extensions and just take an overview of your installed extensions and click uninstall for the extensions you’d like to cto remove completely.

mporarily turn off extensions.

We may not use some extensions often but they might be useful at times. Uninstalling them may not be the right idea because when you need it, it takes time to go to that extension page again for installing it. So better we turn-off these extensions temporarily by disabling them so that we can re-enable them just-in-case. Click the wrench icon > tools > extensions and click disable for the extensions you’d like to temporarily remove.

Keep an eye on “Background Pages”.

Gmail lets you know when you have a new message as it works in background. In the similar way many Google Chrome extensions and web apps use background pages for carrying out their functions. Background pages work behind the browser to deliver better user interface and improved functionality. These pages are invisible but they constantly work in the background. In parallel they use considerably more CPU usage.

Click the wrench icon and select “View background pages” to view the applications that are running invisibly behind the browser. Although task manager (Wrench icon > tools  > Task manager) and “ View background pages” option display the same content but the latter highlights the background pages so that we can find and end the processes that take more CPU resources.

Disable “Continue running background apps when Google Chrome is closed”

For providing more functionality some Google Chrome applications run in background even after we close the browser. Mainly the apps that deliver notifications such as email, social networking sites run all the time. In Chrome developer version, by default the background app feature is active. Go to options > Under the Hood and uncheck “Continue running background apps when Google Chrome is closed”.

Clear Chrome Browser Cache.

The more you browse on the Chrome, the more the cache is flooded up with files. This huge dump of files in the cache may considerably decrease the performance and consequently may slow down your computer. All you have to do is clear out the browser cache timely. Go to wrench menu> tools> and select “Clear browsing data”

Once in a while, it is recommended to backup chrome bookmarks so that it can help you if your browser gets crashed at any moment.


  1. I did it all and it might have been useful, but… was still 100% of CPU most of the time (on a dual core)
    Then I found I could clean my fan. Unmounted the laptop, found walls of dust. Remounted. Much better!

  2. good advice; behaves much better after disabling most plugins at
    there were a lot of them, mostly unneeded. Now not so many threads and CPU is reasonable, coasts at less than 5% rather that the 50% I was seeing.
