Google is making some progress to work on one of Chrome's worst issues: its memory problems. Neowin reports that starting with version 45, Chrome will start clearing up unused RAM when you're not using a tab. On top of this, the browser also changes the way it restores tabs:
With version 45, Chrome will now start prioritising which tabs to open when you restore tabs - or choose the option to 'continue where you left off'. The tabs which you viewed most recently will be loaded first, allowing you to quickly get back to what you were doing before Chrome crashed or you accidentally closed the window. Also, if your computer is low on memory, the browser will stop automatically loading all tabs, focusing only on those deemed important.
In the meantime, when you're not using a tab, the browser will start clearing up unused RAM, with the company expecting improvements of as much as 10%. A test on Gmail showed even more, saving approximately 25% memory compared to Chrome 43.
