If you have got a bunch of tabs open, the background tabs may consume way too many resources and hamper system performance and browsing experience. Microsoft Edge has launched Sleeping Tabs to reduce memory, CPU, and battery consumption to address this. Microsoft today has added an option to Edge 94 to put inactive tabs to sleep almost Immediately i.e within “Less than a minute of activity“.
Microsoft built Sleeping Tabs on Chromium’s Freezing technology.
Where, opposite to tab discarding that requires the page to fully reload, freezing pauses a tab.
To differentiate from normal tabs, Edge fades out Sleeping Tabs.

When you click on a Sleeping Tab, Tab will un-fade and becomes active.
While Microsoft is mulling whether to offer an option to put individual tabs to sleep, the company has brought another viable option where inactive tabs get grayed out and free resources in less than 60 seconds when chosen.
By default, tabs in Microsoft Edge go to sleep after 2 hours of inactivity.
You can adjust the time interval to as minimum as 5 minutes, now to, a few seconds with the new time interval option available in edge://settings/system.
