Chrome 91 is 23% faster thanks to these changes
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, aside from the new features, the update also brings a performance improvement under the hood. According to the company, Chrome 91 is 23% faster than the previous version, thanks to some underlying changes.
With Chrome 91, the company made some improvements to the V8 engine which resulted in a significant increase in performance. Specifically, Google introduced “a new Sparkplug compiler and built-in short calls”. This apparently saves “over 17 years” of CPU time for Chrome users every day.

However, for some processors, “calling functions that are farther from your generated code may cause internal processor optimizations to fail,” Thomas writes in the blog. With short built-in calls, the built-in functions are copied to the same memory region as the generated code. This will prevent these optimization failures.
In simpler terms, these are underlying changes that make Chrome browser faster than before. If you want to know more about the technical aspects of these changes, you can go to the Blog V8. Google says there are more improvements to come for its browser.
