(please be noted we reported "[mm/page_alloc] 39907a939a: netperf.Throughput_Mbps -18.1% regression" on https://lore.kernel.org/all/20220228155733.GF1643@xsang-OptiPlex-9020/ while the commit is on branch. now we still observe similar regression when it's on mainline, and we also observe a 13.2% improvement on another netperf subtest. so report again for information) Greeting, FYI, we noticed a -18.0% regression of netperf.Throughput_Mbps due to commit: commit: f26b3fa046116a7dedcaafe30083402113941451 ("mm/page_alloc: limit number of high-order pages on PCP during bulk free") https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git master in testcase: netperf on test machine: 128 threads 2 sockets Intel(R) Xeon(R) Platinum 8358 CPU @ 2.60GHz with 128G memory with
