Microsoft Edge is getting a performance mode on Windows 10

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

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

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.
