Taming the memory usage in Chrome






Recently I noticed that the 8 GB of Ram on my developer machine never was enough and I got Windows messages quite often about shutting down programs or I would lose information. Ram is cheap these days so I ordered another 8 GB right away, but I was at the same time curious of what it could be that used so much.

I quickly noticed Chrome’s extensive memory usage, around 3 GB, and thought it can’t be normal. When this clip was taken I was only using one Chrome window with 5 tabs open!

After some googling I realized – it is normal for Chrome, but there are things you can do about it.

  1. Where is the memory being used? Chrome has a good way of displaying where the memory is being used. Type chrome://memory-redirect/ in your browser and you’ll see exactly where all the memory in chrome is being used. You can see if it’s a tab, extension, plug-in or something else using it. In my case I noticed that the Telerik extension was using way too much – that one had to go.

  2. De-activate extensions Type chrome://extensions/ in the address window and you’ll be able to see, and also de-activate, extensions in Chrome.
  3. Add an extension to help you with the tabs Having many open tabs take a big chunk of memory. But don’t worry – there’s help. Here are a few extensions that can assist you:
    • Tab Hibernation :: Tab Hibernation frees some memory and CPU on your computer by killing all inactive tabs. Your tabs won’t get lost and you can restore them with a single mouse click.
    • The Great Suspender :: Unload, park, suspend tabs to reduce memory footprint of chrome.
    • Tabs Outliner :: The Next Generation Session Manager; A Really Working Too Many Open Tabs Solution; And Your Browsing Notebook.
