New Chrome throttles tabs
 

Saving processing power

Starting with Chrome 57 Google has started limiting the amount of resources background tabs can use.


Chrome 57 will temporarily delay a background tab's JavaScript timers if that tab is using more than 1 per cent of a CPU core. All background timers are suspended automatically after five minutes on mobile devices.

The suspension will halt resource consumption and cut down on battery usage. It means that those who have hundreds of tabs open, because they never know when they will need them, will no longer have their PC go sleepy bye-bye under the pressure.

Google hinted in late January that it would limit JavaScript timers in background tabs, but nobody expected it to happen as soon as the recent Chrome release.
