Chrome 91 Benchmarks On Linux Showing Off Even Better Performance

Yesterday the Chromium Blog published a new post outlining that Chrome 91 can be up to 23% faster and "saves over 17 years of CPU time daily". The Chrome 91 speed-ups come thanks to the new Sparkplug compiler, short built-in calls, and other work.
Following that post, I began running some benchmarks. I can indeed confirm that Chrome 91 is faster than Chrome 90, but at least in the web benchmarks being run, not seeing ~23% faster but generally faster by single digit percentages over the prior Chrome 90 stable.
From JetStream 2 to ARES-6 to WebXPRT to MotionMark and other browser benchmarks, Chrome 91 had a number 2~6% speed-ups on the Ryzen 5 5500U laptop used for these initial tests.
While not seeing anything close to 23% in these particular benchmarks compared to the prior release, when comparing against the latest Firefox, Chrome continues coming out ahead in these browser tests:
Those are the browser tests on Ubuntu with a Ryzen 5 laptop while seeing similar outcome on other systems. More tests ongoing but so far nothing else standing out in these tests beyond a few percentage point improvements for Chrome 91 on Linux.
