Microsoft is releasing the "sleeping tabs" feature in the Chromium-based Web Edge browser, which will drastically reduce memory and CPU usage.
The new feature is available to all users running Microsoft Edge Beta 88 after its initial launch in September as a Microsoft Edge experiment.
"To improve the memory and CPU usage browser"We have launched the 'sleeping tabs,'" said the Microsoft Edge team.
"Just as a good night's sleep allows you to stay productive and relaxed the next day, sleeping tabs help optimization of your browser performance as it frees up resources for the tabs you are actually using.
The feature will cause inactive tabs to "switch to standby mode" automatically to free up system resources (memory and CPU) after a predetermined period of time, resources that can be redirected to recently opened tabs to already existing or in other applications.
How sleeping tabs work
"Sleeping tabs are based on the core of Chromium freezing technology," explained Eleanor Huynh, Microsoft's chief program manager, when the feature was first announced.
"Freezing pauses the script timers of a tab to minimize resource usage. A sleeping tab automatically continues to function click on it, which differs from the rejected tabs, which require full loading of the page."
Sleep tabs will reduce memory usage by an average of 32%, in most cases, and lead to about 37% lower CPU usage compared to non-sleep tabs.
"When you use sleeping tabs, some sites may not work as expected after sleep," the Microsoft Edge team added. "To maintain your flow, we have created heuristics to detect these scenarios and prevent these tabs from sleeping ”.
By default, inactive tabs will be automatically "suspended" after two hours of inactivity, but this interval may change if you go to the "Settings" page available at edge: // settings / system.
Waking up the tab is simple, just click on it and you can also add sites that you do not want to be affected by this feature to a block list on the same page as settings.
