Several Google Chromebooks, particularly the lower-priced models, come with just 2 GB of memory and for some, that’s just not enough. What often happens is that as more browser tabs are opened, data on older tabs simply disappears. These tabs have to be refreshed and that’s not ideal, especially if those tabs are being used for any communications or media consumption.

The problem happens on Chromebooks with 4 GB of RAM as well, but much less often. Still, even on the Chromebook Pixel, I experience it from time to time. The good news is that regardless of your Chromebook model, one quick command line with a restart can definitely help. The solution uses zRam or compressed swap space and you can use it on a Chromebook because it’s part of Linux, which is the underlying core of a Chrome OS device.
