Google Chrome 57 adds performance improvements

Google has announced that Chrome 57 will throttle individual background tabs by limiting the timer fire rate for background tabs using excessive power.

“Efficient power usage is an important aspect of speed. To prolong battery life, Chrome should minimise power impact from things users can’t see,” said Google.

“This includes background tabs, which consume a third of Chrome’s power usage on desktop.”

Google said Chrome has limited timers in the background to run once per second.

“Via the new throttling policy, Chrome 57 will delay timers to limit average CPU load to 1% of a core if an application uses too much CPU in background.”

Tabs playing audio or maintaining real-time connections – like WebSockets or WebRTC – won’t be affected.
