Last week Google rolled out the Chrome 91 update on the stable channel. The latest version of the browser introduces tons of new features and improvements including support for default desktop mode on large screen devices, revamped controls, and the ability to freeze Tab Groups. But, apart from the new features, the update also brings some performance improvement under the hood. According to the company, Chrome 91 is 23 percent faster than the previous version, thanks to some underlying changes.
With Chrome 91, the company has made some improvements to the V8 engine that enabled a significant performance boost. Specifically, Google has introduced “a new Sparkplug compiler and short builtin calls”. This apparently saves “over 17 years” of CPU time for Chrome users each day.

However, for some CPUs, “calling functions that are further away from your generated code can cause CPU-internal optimizations to fail,” Thomas writes in the blog. With Short builtin calls, the builtin functions are copied into the same memory region as the generated code. This will avoid those optimization failures.
In simpler terms, these are some underlying changes that make the Chrome browser faster than it was before. If you want to know more about the technicalities of these changes, you can head over to the V8 blog. Google says there are more improvements to come for its browser.
