please be noted we reported "[linux-next:master] [mm] f1a7941243: unixbench.score -5.1% regression" on https://lore.kernel.org/all/202212051324.182a6363-yujie.liu@intel.com/ when this commit was on linux-next now after this commit was already merged to mainline, by other options in unixbench testing, we noticed regression is still existing. report again FYI. below is the full report. Greeting, FYI, we noticed a -19.2% regression of unixbench.score due to commit: commit: f1a7941243c102a44e8847e3b94ff4ff3ec56f25 ("mm: convert mm's rss stats into percpu_counter") https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git master in testcase: unixbench on test machine: 128 threads 4 sockets Intel(R) Xeon(R) Gold 6338 CPU @ 2.00GHz (Ice Lake) with 256G memory with following parameters: runtime: 300s nr_task: 30% test: spawn cpufreq_governor: performance test-description: UnixBench is the original BYTE UNIX benchmark suite aims to test performance of Unix-like system. test-url: https://github.com/kdlucas/byte-unixbench In addition to that, the commit also has significant impact on the following tests:
