[mm/page_alloc] f26b3fa046: netperf.Throughput_Mbps -18.0% regression

by kernel test robot

(please be noted we reported "[mm/page_alloc] 39907a939a: netperf.Throughput_Mbps -18.1% regression" on https://lore.kernel.org/all/[email protected]/ 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

[io_uring] 584b0180f0: phoronix-test-suite.fio.SequentialWrite.IO_uring.Yes.Yes.1MB.DefaultTestDirectory.mb_s -10.2% regression

by kernel test robot

Greeting, FYI, we noticed a -10.2% regression of phoronix-test-suite.fio.SequentialWrite.IO_uring.Yes.Yes.1MB.DefaultTestDirectory.mb_s due to commit: commit: 584b0180f0f4d67d7145950fe68c625f06c88b10 ("io_uring: move read/write file prep state into actual opcode handler") https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git master in testcase: phoronix-test-suite on test machine: 96
