Greeting, FYI, we noticed a -12.0% regression of fxmark.ssd_btrfs_MWRM_72_directio.works/sec due to commit: commit: e3588283e94f85ef79c2f5529c452d02c7360988 ("btrfs: balance btree dirty pages and delayed items after a rename") https://git.kernel.org/cgit/linux/kernel/git/next/linux-next.git master in testcase: fxmark on test machine: 128 threads 2 sockets Intel(R) Xeon(R) Platinum 8358 CPU @
