Greeting, FYI, we noticed a -13.2% regression of aim7.jobs-per-min due to commit: commit: 2996e1f8bcadf0436cc67b63af01523f6cf5d43f ("btrfs: factor our read/write stage off csum_tree_block into its callers") https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git master in testcase: aim7 on test machine: 72 threads Intel(R) Xeon(R) Gold 6139 CPU @ 2.30GHz with 128G memory with following parameters: disk: 4BRD_12G md: RAID0 fs: btrfs test: sync_disk_rw load: 20 ucode: 0x200005e cpufreq_governor: performance test-description: AIM7 is a traditional UNIX system level benchmark suite which is used to test and measure the performance of multiuser system. test-url: https://sourceforge.net/projects/aimbench/files/aim-suite7/ In addition to that, the commit also has significant impact on the following tests: +------------------+-----------------------------------------------------------------------+ | testcase: change | aim7: aim7.jobs-per-min -19.1% regression | | test machine |
