Subject: [net] 02dcea6024: netperf.Throughput_tps -9.1% regression
Greeting,
FYI, we noticed a -9.1% regression of netperf.Throughput_tps due to commit:
commit: 02dcea6024d411cda23bd77e5e604f94a32c332d ("net: allow sk_prot->release_cb() without sock lock held")
https://github.com/ammarfaizi2/linux-block axboe/linux-block/sock-nolock.2
in testcase: netperf
on test machine: 128 threads 2 sockets Intel(R) Xeon(R) Gold 6338 CPU @ 2.00GHz with 256G memory
with following parameters:
ip: ipv4
runtime: 300s
nr_threads: 25%
cluster: cs-localhost
test: TCP_RR
cpufreq_governor: performance
ucode: 0xd000331
test-description: Netperf is a benchmark that can be use to measure various aspect of networking performance.
test-url: http://www.netperf.org/netperf/
If you fix the issue, kindly add following tag
Reported-by: kernel test robot <oliver.sang@...el.com>
Details are as below:
-------------------------------------------------------------------------------------------------->
To reproduce:
git clone https://github.com/intel/lkp-tests.git
cd lkp-tests
sudo 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
sudo bin/lkp run generated-yaml-file
# if come across any failure that blocks the test,
# please remove ~/.lkp and /lkp dir to run from a clean state.
