Chrome puts ‘uninteresting’ tabs on sidetracked in low memory




Google’s Chrome team test functionality “uninteresting” tabs from the memory retrieves if there is not enough available memory left. The page is retrieved again when clicking the tab. It is unclear how Google determines which tabs ‘interesting’.

The functionality is present in the experimental Canary version of Chrome, and can be activated via the location chrome: // flags / # enable-tab discarding. After restarting Chrome displays the list of open tabs with tabs at the top of the most interesting and at the bottom the least interesting. “The least interesting can be discarded if we come short of physical memory”, is the message.

The tab then remains in the tab list, but the page is no longer open. Once you click on the tab, the page is retrieved. Tabs may also be manually dumped. It is not clear based on which features a Chrome tab as ‘interesting’ designates. This seems to be one of the ways that the Chrome-team in order to keep test systems with a lot of open browser tabs responsive. The function is described by Google developer François Beaufort. The feature is already in Chrome OS.

The function is similar to what the extension The Great Suspender does. Who activates the extension given the option to all the tabs that the user a predetermined time do not click, automatically freeze. That should also care in memory usage.
