Subject: [fs] aec499039e: unixbench.score 19.2% improvement
Greeting,
FYI, we noticed a 19.2% improvement of unixbench.score due to commit:
commit: aec499039e7b21224ef29e5a2daba328aec14442 ("[PATCH] fs: Optimized file struct to improve performance")
url: https://github.com/0day-ci/linux/commits/Shaokun-Zhang/fs-Optimized-file-struct-to-improve-performance/20210409-114859
base: https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git 5e46d1b78a03d52306f21f77a4e4a144b6d31486
in testcase: unixbench
on test machine: 96 threads Intel(R) Xeon(R) CPU @ 2.30GHz with 128G memory
with following parameters:
runtime: 300s
nr_task: 30%
test: syscall
cpufreq_governor: performance
ucode: 0x4003006
test-description: UnixBench is the original BYTE UNIX benchmark suite aims to test performance of Unix-like system.
test-url: https://github.com/kdlucas/byte-unixbench
Details are as below:
-------------------------------------------------------------------------------------------------->
To reproduce:
