Google has made some optimisations for the macOS version of the Chrome browser, resulting in significant speed improvements. And as a result, the browser's performance on Apple's Speedometer browser benchmark has surpassed previous levels and is currently faster than ever, says the company in a blog post.
Google has revealed that the latest version of Chrome has undergone significant optimization efforts to enhance its speed and efficiency. This involved improved parsing for specific CSS and JavaScript functions and more efficient pointer compression.
Additionally, targeted optimisations were made for commonly used functions such as Object.prototype.toString and Array.prototype.join.
The team also improved CSS's InterpolableColor and innerHTML parsing for updating the DOM via JavaScript. Interestingly, this work is expected to benefit WebKit as well, as they plan to incorporate it into their engine. Ultimately, these optimisations aim to improve the overall web experience for all users.
Google optimised pointer compression and decompression in both V8 and Oilpan, ensuring not to compress high-traffic fields. Frequently accessed objects, such as "undefined," were relocated to the beginning of memory bases for faster access.
These optimisations led to a 10% performance increase on Apple's Speedometer 2.1 browser benchmark in just three months.
Google improves Chrome on high-end smartphones
Chrome on Android has always been designed to use minimal resources, but different Android devices have varying capabilities. To improve Chrome's performance on high-end devices, Google has created a version that prioritises speed over binary size. This version uses compiler flags tuned for speed and runs the Speedometer 2.1 benchmark 30% faster on capable devices.
