📢 Microsoft Edge 100 features Sleeping Tabs improvement

What is the sleeping tabs feature in Microsoft Edge?

The sleeping tabs are based on Chrome's "freezing" technology, but way better than that. Freezing pauses a tab's script timers to minimize resource usage. A sleeping tab resumes automatically when clicked, which is different than discarded tabs, which require the page to fully be reloaded.

This feature allows inactive background tabs to "go to sleep", releasing system resources after a set amount of time. These resources include both memory and CPU and can be used for new or existing tabs or other applications running on your device.

By default, Microsoft sets the tabs to go to sleep after two hours of inactivity. If two hours isn't right for you, you can choose a different time interval for the Microsoft Edge tab to go to sleep.

The feature was first rolled out in Microsoft Edge Canary build 87.0.643.0, and later it has seen many improvements.

What's new and improved in Microsoft Edge Sleeping Tabs

Microsoft recently highlights the improvements made in Microsoft Edge 100. Beginning in Microsoft Edge 100, we’ve updated sleeping tabs to enable pages that are sharing a browsing instance with another page to now go to sleep, according to the Microsoft blog post.

The company says that with this change, 8% more tabs on average will sleep, which will now save even more resources for you. The company claims that on average, each sleeping tab saves 85% of memory and 99% of CPU for Microsoft Edge.

You can now find out how much memory the sleeping tabs feature in Microsoft Edge is saving for you by visiting the Performance under the “…” (“Settings and more”) menu.
