至少这个没啥用
Sudarsan Mahendran commented on the mailing list:
"I ported this patch series on top of v6.17 and ran some benchmarks: will-it-scale, hackbench, redis, unixbench and kernbench. I ran the benchmarks on Intel Granite Rapids (480 cores), AMD Turin (512 cores) and ARM (80 cores)
Summary of the results:
- Significant change (meaning >10% difference between base and experiment) on will-it-scale tests in AMD.
- No significant change on other benchmarks ran."
严谨一点的解读是，三家都测了，只有AMD出现10%以上提升
结合后文，提升是
Going over his benchmarks on that LKML thread were exciting when seeing "+28.58%" mean improvements to get started, but also some 13~20% regressions... But when getting to the higher process counts for these scalability benchmarks was when it was getting really wild with +70.59%, +126.89%, +112.89%, and other massive wins. See all of the Google engineer's data in this thread. |
