After Sleeping Tabs and Startup boost, Microsoft is testing a new performance feature for the Edge browser. The feature called “Performance mode” when enabled, optimizes CPU, battery usage, speed, responsiveness, and memory. The feature is available to some users via staged rollout, you can enable it now. Here’s how.

When you browse online, you do most of the things: you open many tabs, work on a project, watch videos and attend online meetings. All these require a lot of resources, hence you feel the pages are loading slow.
To address this, based on Chromium tab freezing, Microsoft introduced Sleeping tabs to put the inactive tabs after a certain amount of time to sleep. When tabs were asleep, those resources will be freed. The tabs will be loaded when you select them like normal tabs.
The Redmond software giant also wants Edge to start faster when you click its icon on the desktop or start menu. Edge loads fast when you enable the Startup boost feature.
Other than the above two features, Micorosft is experimenting with Performance Mode. The company hasn’t officially announced this yet but says performance gains may differ for each as they depend on browsing habits and device configuration. So, we’ve very little information available.
We don’t know how this feature works and the potential performance benefits unless Edge teams come out with a blog post.
Enable Performance Mode in Microsoft Edge
- Ensure you’re running Edge Canary 91.0.859.0 or later,
- Right-click on its shortcut on the desktop
- In the Target field after giving a space append the following switch
--enable-features=msPerformanceModeToggle - Click apply.
- Open Canary, click on Settings, and more
- Select System, Under Optimize Performance, click on the dropdown arrow, and select “Always on” for Performance Mode.
You need to set the option to Always off to disable Performance Mode in the Edge browser.
This could be an extension of the Sleeping tabs.
