Performance Improvements in Chrome M87
Tab throttling and Occlusion Tracking
Tab throttling
Google has prioritized how Chrome 87 handles tabs. The browser now prioritizes active tabs versus everything that’s open, which Google said will reduce CPU usage by up to 5x and extend battery up to 1.25 hours.
Google started testing, throttling background JavaScript timers to enhance battery life, and therefore the company’s work has resulted in marked improvement.
Occlusion Tracking
which was previously added to Chrome OS and Mac to Windows, allows Chrome to understand which windows and tabs are literally visible to you.
With this information, Chrome can optimize resources for the tabs you are using, not those you have minimized, making Chrome up to 25% faster to start up and 7% faster to load pages, all while using less memory.
These updates are going to be gradually rolling out in M87 and our next release M88, says Google.
Back/forward cache
Google roll out the back/forward cache feature to Google Chrome for Android users in a gradual launch.
“Back/forward cache is a browser optimization that permits instant back and forwards navigation.
It significantly improves the browsing experience for users especially those with slower networks or devices,” Google explains.
This feature will store an entire snapshot of the web page, including the JavaScript memory, within the cache so you will instantly go back and forward between sites and to return to the content right where you left off.
In Chrome 87, our back/forward cache will make 20% of those back/forward navigations instants, with plans to extend this to 50% through further improvements and developer outreach within the near future, says Google.
