Microsoft Edge is an incredible desktop browser, packing basically all important features available on the market today. Microsoft is now working on a new feature called “performance mode”, designed specifically for performance, especially when you’re gaming or using other apps.

In 2020, Microsoft introduced Sleeping Tabs to reduce the amount of RAM and CPU (processing) power used by the browser. This feature alone isn’t enough to improve the overall system performance as there are factors affecting Edge’s RAM and CPU usage on Windows 10.

As shown in the screenshot below, Microsoft Edge is now adding a new “Performance mode” option to the System settings of the browser. When enabled, Edge will try to optimize overall web browsing speed, responsiveness and reduce CPU, RAM and battery usage without affecting the overall experience.

However, Microsoft noted that the performance improvements will vary and the result ultimately depends on users browsing habits.

Performance mode in Microsoft Edge aims to reduce overall resources usage

In our tests, we observed that that “performance mode” forces Sleeping Tabs when tabs are inactive for five minutes.

By default, sleeping tabs are set to go to sleep after two hours of inactivity. When performance mode is enabled, Edge will discard tabs after only five minutes of inactivity and you can still wake up a sleeping tab by simply clicking on it.

Microsoft Edge will also detect heavy resources activity in the background (such as audio or video) and block those tabs from sleeping. As you may be aware, Edge’s sleeping mode is based on a core Chromium technology that prevents background activities and scripts to minimize resource usage while saving the browsing data.

This should cut down memory, CPU and battery usage in most cases. In addition to the sleeping tab, Edge’s performance mode will also tweak other browser settings to improve the performance.

It’s worth noting that all sites and browser features work as before after enabling the performance mode.

The feature is currently available in Microsoft Edge Canary 91 for select users and should make its way into the stable release later this year.
