The first, and probably most important, part of Chrome 45 is a new method of saving memory on running tabs. Now, it will detect when a webpage isn’t busy with some other task and use that time to clean up old memory. Google has found that this will save an average of 10 percent of memory on most tabs, and for more advanced Web apps like Gmail, it found that it can save up to 25 percent, which is certainly substantial for users who are pushing their memory to the limit when using Chrome.
There’s also a new feature that will help improve the launch speed of the browser for users who choose to have Chrome remember where they left off. They’ll restore from most to least recently viewed, and if it runs out of memory, it will stop restoring tabs until the user clicks on it manually.
Since Flash is always an issue with resources, Chrome 45 will further implement Google’s feature that auto-pauses Flash content that’s not central to a website’s core functionality. Google found that implementing this feature can save up to 15 percent of a user’s battery life. Over the next few weeks, the team plans to make this feature on by default for all users.
Chrome 45 is available for desktop users of the browser now.
