Subject: [fs] 936e92b615: unixbench.score 32.3% improvement
Greeting,
FYI, we noticed a 32.3% improvement of unixbench.score due to commit:
commit: 936e92b615e212d08eb74951324bef25ba564c34 ("[PATCH RESEND] fs: Move @f_count to different cacheline with @f_mode")
url: https://github.com/0day-ci/linux/commits/Shaokun-Zhang/fs-Move-f_count-to-different-cacheline-with-f_mode/20200624-163511
base: https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git 5e857ce6eae7ca21b2055cca4885545e29228fe2
in testcase: unixbench
on test machine: 192 threads Intel(R) Xeon(R) Platinum 9242 CPU @ 2.30GHz with 192G memory
with following parameters:
runtime: 300s
nr_task: 30%
test: syscall
cpufreq_governor: performance
ucode: 0x5002f01
test-description: UnixBench is the original BYTE UNIX benchmark suite aims to test performance of Unix-like system.
