[btrfs] 59c7b566a3: fsmark.files_per_sec 2.3% improvement Greeting, FYI, we noticed a 2.3% improvement of fsmark.files_per_sec due to commit: commit: 59c7b566a3b653fe7865cef007c053fd88de8317 ("btrfs: index free space entries on size") https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git master in testcase: fsmark on test machine: 128 threads 2 sockets Intel(R) Xeon(R) Platinum 8358 CPU @ 2.60GHz with 128G memory with following parameters: iterations: 1x nr_threads: 1t disk: 1HDD fs: btrfs filesize: 4K test_size: 80M sync_method: fsyncBeforeClose nr_files_per_directory: 1fpd cpufreq_governor: performance ucode: 0xd000280 test-description: The fsmark is a file system benchmark to test synchronous write workloads, for example, mail servers workload. test-url: https://sourceforge.net/projects/fsmark/ In addition to that, the commit also has significant impact on the following tests:
