Subject: [xfs] fdbb8c5b80: aim7.jobs-per-min 3.9% improvement
Greeting,
FYI, we noticed a 3.9% improvement of aim7.jobs-per-min due to commit:
commit: fdbb8c5b805c19bc2764aa1b91952e75e4c1c086 ("xfs: devirtualize ->data_entsize")
https://git.kernel.org/cgit/linux/kernel/git/next/linux-next.git master
in testcase: aim7
on test machine: 72 threads Intel(R) Xeon(R) Gold 6139 CPU @ 2.30GHz with 128G memory
with following parameters:
disk: 1BRD_48G
fs: xfs
test: disk_wrt
load: 3000
cpufreq_governor: performance
ucode: 0x2000065
test-description: AIM7 is a traditional UNIX system level benchmark suite which is used to test and measure the performance of multiuser system.
test-url: https://sourceforge.net/projects/aimbench/files/aim-suite7/
Details are as below:
