Chrome 45 Frees Up Memory For A Faster And More Efficient Web

Chrome’s performance has never bothered me, but I know it feels like a memory hog to others based on user feedback. Google’s latest update looks to alleviate that, and also brings other improvements such as power savings and better tab restoration.

Chrome can now detect when a webpage isn't busy with some other task, and use the free time to aggressively clean up old, unused memory. In practice we found that this reduced website memory usage by 10% on average, but the effect is even more dramatic on complex web apps. With Gmail, for example, we can free up nearly a quarter of the memory used by the tab.
