Google’s Chrome is popular but it has earned itself something
of a reputation for being a resource-hungry browser. Microsoft
Edge is also based on Chromium (the platform that powers
Chrome), but the tech giant has taken various measure to
improve things, and address poor performance concerns.
With a new feature, Microsoft is planning to cut down the
animations when you’re not actively using Edge browser. This
change is part of the performance mode, which was introduced
earlier this month.
Edge (Canary) was recently updated with a new “performance
mode” which will give it a boost over rival browsers on
Windows 10. The experimental performance mode attempts to
optimize both CPU and RAM usage to reduce battery/power
consumption while ensuring browsing speed and responsiveness.
Thanks to the new update, those running macOS will soon benefit
from improved performance mode too. In addition to macOS
support, Microsoft Edge’s settings page was also updated with
additional information on the upcoming performance mode.
Microsoft now states that performance improvements will vary
depending on your device configurations and browsing habits,
but users will notice at least three changes after turning on
the optional feature.
The company warned that video streaming will be less smooth
when you use performance mode. Likewise, Microsoft Edge
animations will also slow down when you’re not interacting with
Microsoft is implementing these changes to reduce CPU usage and
improve overall battery life.
The third change is for default sleeping tabs behaviour.
Microsoft has confirmed that the background/inactive tabs will
be discarded (go to sleep) after five minutes of inactivity
instead of two hours.
Currently, when you enable sleeping tabs, Edge puts tabs to
sleep after two hours by default.
How to test performance mode
Microsoft Edge performance mode is coming to both Windows 10
and macOS later this year. It’s currently hidden behind an
experimental flag, but you can enable it by following these
On macOS, launch terminal (bash) after updating Edge Canary to
version 92 and enter the following command:
/Applications/Microsoft Edge Canary.app/Contents/MacOS/Microsoft Edge Canary --enable-features=msPerformanceModeToggle
On Windows 10, you can simply right-click on the Edge Canary
shortcut and append the following command in the Target field:
You can also run the executable file of the browser from the
command line with the above code on the end.
