Subject: [btrfs] cb49511328: aim7.jobs-per-min 3.1% improvement
Greeting,
FYI, we noticed a 3.1% improvement of aim7.jobs-per-min due to commit:
commit: cb49511328dcce73840a54661622950d7fa6384e ("btrfs: define separate btrfs_set/get_XX helpers")
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.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: 4BRD_12G
md: RAID1
fs: btrfs
test: sync_disk_rw
load: 20
cpufreq_governor: performance
ucode: 0x2000064
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:
