Subject: [lkp] [f2fs] b873b798af: fsmark.files_per_sec 73.0% improvement
FYI, we noticed a 73.0% improvement of fsmark.files_per_sec due to commit:
commit b873b798af6386f3c7ca1636d4989e9b8f9d1794 ("Revert "f2fs: use percpu_rw_semaphore"")
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git master
in testcase: fsmark
on test machine: 72 threads Intel(R) Xeon(R) CPU E5-2699 v3 @ 2.30GHz with 128G memory
with following parameters:
iterations: 8
disk: 1SSD
nr_threads: 4
fs: f2fs
filesize: 9B
test_size: 40G
sync_method: fsyncBeforeClose
nr_directories: 16d
nr_files_per_directory: 256fpd
cpufreq_governor: performance
The fsmark is a file system benchmark to test synchronous write workloads, for example, mail servers workload.
Disclaimer:
Results have been estimated based on internal Intel analysis and are provided
for informational purposes only. Any difference in system hardware or software
design or configuration may affect actual performance.
