Build 2021: Edge 91 will be the best-performing browser with Sleeping tabs and Startup boost

Microsoft at Build 2021 announced an upcoming release of Microsoft Edge, version 91, which will include several new features designed to improve the browser performance on low-end devices. Specifically, these features include Sleeping Tabs and Startup Boost to keep Microsoft Edge fast and responsive.

If you are following our Edge coverage you may remember that the "Sleeping Tabs" feature will automatically suspend a tab if this tab has not been used for a certain amount of time and was in the background. If you click on such a sleeping tab, the browser will quickly restore it in memory. This cool feature will save device's RAM resources, so even devices with a small amount of memory will be able to work with the large number of open tabs. Unused tabs will be automatically unloaded from memory.

Startup Boost keeps several of Edge’s processes in the background with minimal resource footprint to help launch the browser significantly faster. The processes prepare and load important components of the browser once the user sign in to his Windows account. Startup Boost was temporarily disabled in recent Edge preview versions, but it will become available to the public in version 91.

Microsoft Edge 91 is currently available in the Beta channel. The stable version is expected to become available this week.
