How many tabs do you normally open up when browsing the web? You might be unaware that the more tabs opened in a web browser the more memory your computer will have to process. With memory being processed on your computer, it can make your system appear to be a bit bogged down. Instead of having to close out all those tabs within Google Chrome a new feature will allow users to keep their tabs open within the Google Chrome web browser but suspend certain tabs that are not priority which will ultimately mean that these tabs won't be taking up your memory.
Google is attempting to bring on a feature that has already been available through their Chrome OS. This particular feature would be able to maintain and control your Google Chrome tabs and cut off anything that it believes will eat up memory when it's not currently being viewed. As mentioned, the new tabs feature will suspend your tabs from withdrawing any unnecessary memory. Suspending can sound alarming but you won't have to worry about Google deleting any tabs by itself as the tabs will still be present within the web browser. Additionally, Google will be able to determine which tabs to suspend until they are clicked on once again. Tabs that have audio, an application running or pinned tabs will be ranked within Chrome to assure that these tabs will not be suspended or cause a disruption while on the computer.
According to the Chromium web page, the official ranking system that Chrome will follow to suspend tabs are as follow:
"Internal pages like new tab page, bookmarks, etc. Tabs selected a long time ago. Tabs selected recently. Tabs playing audio. Apps running in a window. Pinned tabs. The selected tab"
Currently, Google is working on the update and feature to bring over onto Windows, Mac OS along with Linux. The development of this feature is currently available through Google's nightly build channel for those who are interested in trying out the feature before it rolls out onto the official build release but as of right now, it's unknown just when the new feature will make its way to the general public.
