Microsoft Edge update to reduce CPU, memory and battery usage

Microsoft Edge memory usage

Although Edge is faster than Google Chrome on Windows 10,
Microsoft’s flagship browser still eats RAM more than the
legacy Edge on most computers.

Now, a new change to the browser that is now available in the
Edge Canary update opens the door for Microsoft to reduce both
memory and CPU usage when you’re not actively using tabs.

The feature is called Sleeping tabs and it aims to put your
tabs to sleep. When implemented, it shows a memory reduction of
up 26% and CPU reduction of up to 29% in early tests.

This feature is in addition to existing “SegmentHeap”, which is
already being used by Microsoft’s Edge browser to reduce memory
usage by up to 27%. According to the tech giant, all these
improvements together should result in “excellent battery
savings” on laptops and 2-in-1s.

Microsoft Edge 87 (Canary) introduces tab resources management
improvements to give you greater control over the tabs.

The short story is that Edge will put background tabs to sleep
automatically to reduce overall memory and CPU usage, which
will contribute to battery savings.

Edge Canary sleeping mode

Apparently, Microsoft Edge new tab resources management feature
is based on Chromium’s “freezing” feature. With sleeping tabs
and Chromium’s freezing technology, Microsoft aims to freeze
the contents of the tab. When frozen, Edge will stop tabs from
performing actions and running script until you interact with
tabs again.

By default, your browsing tabs will go to sleep after you don’t
use it for two hours.

Unlike Chrome’s freeze tab feature, Microsoft says Edge will
allow you to choose a different time interval in Settings >
System. If you don’t want Edge to kill off your tabs for
Twitter or Outlook, you can add sites to the whitelist.

Edge performance settings

To enable this feature, you’ll need to install Edge Canary and
enable experimental flags titled ‘Sleeping Tabs’ in
edge://flags menu.

In addition,
Microsoft has also confirmed that they’re working on other
areas to make Chromium Edge faster. Microsoft will likely
explain how it plans to improve Edge’s performance in much more
detail soon.
