Google has introduced a new set of features in Chrome 87 that
could reduce Chrome’s memory and CPU usage significantly on
Windows 10. Google Chrome 87 introduces tab throttling and
other tweaks to make the browser faster on devices with Windows
Google can now better manage your computer resources by
preventing background tabs (inactive tabs) from triggering
Timers to once per minute. Google believes that reducing the
Interesting, background features including push notifications
throttled. According to tests conducted by Chromium developers,
the update could even extend the battery life of some devices.
Google has also confirmed that it’s working on “Occlusion
Track” feature for Windows, but it’s rolling out gradually.
The feature already works well on Chrome OS and it’s finally
coming to Microsoft users.
The concept of Occlusion Track is similar to heatmap as it
allows Chrome to know which windows and tabs are visible to
you. Based on the visibility of the tabs, Chrome will
automatically apply optimization to active tabs and allow users
to access web pages faster.
Currently, any native window from any app could occlude the
root window of the browser, which forces Chrome to
unnecessarily consume resources when a root window is occluded.
After the update, Chrome will receive a signal from the OS to
avoid computation of the occlusion unnecessarily.
In addition, users might notice improvements in the launch time
of Google Chrome for Windows 10.
“This is contributing to increased speed on user’s machines
because we are reducing the power and memory consumption for
occluded foreground tabs to that of non-active background
tabs,” Google said.
For mobile users, Google is improving backwards and forward
It’s worth noting that
Microsoft is also working on a new feature called ‘Sleeping
Tabs’ that will cut down background usage of the inactive
tabs to relocate resources to active tabs.
Google is currently planning to roll out these improvements in
the coming weeks. However, some users may not get the
performance upgrade this year due to the throttled rollout
“There will be a more extensive rollout plan to actually act on
the signal this API is offering in terms of throttling,
discarding, or backgrounding occluded tabs,” the company said.
