Subject: [btrfs] 2996e1f8bc: aim7.jobs-per-min -13.2% regression
Greeting,
FYI, we noticed a -13.2% regression of aim7.jobs-per-min due to commit:
commit: 2996e1f8bcadf0436cc67b63af01523f6cf5d43f ("btrfs: factor our read/write stage off csum_tree_block into its callers")
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: RAID0
fs: btrfs
test: sync_disk_rw
load: 20
ucode: 0x200005e
cpufreq_governor: performance
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/
In addition to that, the commit also has significant impact on the following tests:
