hi, Yosry Ahmed, per your suggestion in https://lore.kernel.org/all/CAJD7tkameJBrJQxRj+ibKL6-yd-i0wyoyv2cgZdh3ZepA1p7wA@xxxxxxxxxxxxxx/ "I think it would be useful to know if there are regressions/improvements in other microbenchmarks, at least to investigate whether they represent real regressions." we still report below two regressions to you just FYI what we observed in our microbenchmark tests. (we still captured will-it-scale::fallocate regression but ignore here per your commit message) Hello, kernel test robot noticed a -36.6% regression of vm-scalability.throughput on: commit: 8d59d2214c2362e7a9d185d80b613e632581af7b ("mm: memcg: make stats flushing threshold per-memcg") https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git master testcase: vm-scalability test machine: 224 threads 4 sockets Intel(R) Xeon(R) Platinum 8380H CPU @ 2.90GHz (Cooper Lake) with 192G memory parameters: runtime: 300s size: 1T test: lru-shm cpufreq_governor: performance test-description: The motivation behind this suite is to exercise functions and regions of the mm/ of the Linux kernel which are of interest to us. test-url: https://git.kernel.org/cgit/linux/kernel/git/wfg/vm-scalability.git/ In addition to that, the commit also has significant impact on the following tests:
