Greeting,
FYI, we noticed a 80.1% improvement of stress-ng.dir.ops_per_sec due to commit:
commit: 80d287de7b49ed673418f4fb91a523c58c5bebf2 ("[PATCH 07/39] xfs: journal IO cache flush reductions")
url: https://github.com/0day-ci/linux/commits/Dave-Chinner/xfs-CIL-and-log-optimisations/20210603-134113
base: https://git.kernel.org/cgit/fs/xfs/xfs-linux.git for-next
in testcase: stress-ng
on test machine: 96 threads 2 sockets Intel(R) Xeon(R) Gold 6252 CPU @ 2.10GHz with 512G memory
with following parameters:
nr_threads: 10%
disk: 1HDD
testtime: 60s
fs: xfs
