Subject: [btrfs] c8eaeac7b7: aim7.jobs-per-min -11.7% regression
Greeting,
FYI, we noticed a -11.7% regression of aim7.jobs-per-min due to commit:
commit: c8eaeac7b734347c3afba7008b7af62f37b9c140 ("btrfs: reserve delalloc metadata differently")
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git master
in testcase: aim7
on test machine: 40 threads Intel(R) Xeon(R) CPU E5-2690 v2 @ 3.00GHz with 384G memory
with following parameters:
disk: 4BRD_12G
md: RAID0
fs: btrfs
test: disk_rr
load: 1500
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/
Details are as below:
-------------------------------------------------------------------------------------------------->
To reproduce:
git clone https://github.com/intel/lkp-tests.git
cd lkp-tests
bin/lkp install job.yaml # job file is attached in this email
bin/lkp run job.yaml
