Subject: [loop] 8883efd909: stress-ng.loop.ops_per_sec 148.4% improvement
Greeting,
FYI, we noticed a 148.4% improvement of stress-ng.loop.ops_per_sec due to commit:
commit: 8883efd909da6648570c698567fd8923bf66a852 ("[PATCH] loop: replace loop_ctl_mutex with loop_idr_spinlock")
url: https://github.com/0day-ci/linux/commits/Tetsuo-Handa/loop-replace-loop_ctl_mutex-with-loop_idr_spinlock/20210827-000519
base: git://git.infradead.org/users/hch/configfs.git for-next
in testcase: stress-ng
on test machine: 96 threads 2 sockets Intel(R) Xeon(R) Gold 6252 CPU @ 2.10GHz with 512G memory
with following parameters:
nr_threads: 100%
disk: 1HDD
testtime: 60s
class: device
test: loop
cpufreq_governor: performance
ucode: 0x5003006
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 split-job --compatible job.yaml # generate the yaml file for lkp run
bin/lkp run generated-yaml-file
