Subject: [vfs] 0be0ee7181: netperf.Throughput_tps 3.0% improvement
Greeting,
FYI, we noticed a 3.0% improvement of netperf.Throughput_tps due to commit:
commit: 0be0ee71816b2b6725e2b4f32ad6726c9d729777 ("vfs: properly and reliably lock f_pos in fdget_pos()")
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git master
in testcase: netperf
on test machine: 16 threads Intel(R) Xeon(R) E-2278G CPU @ 3.40GHz with 32G memory
with following parameters:
ip: ipv4
runtime: 300s
nr_threads: 50%
cluster: cs-localhost
test: UDP_RR
cpufreq_governor: performance
ucode: 0xd6
test-description: Netperf is a benchmark that can be use to measure various aspect of networking performance.
test-url: http://www.netperf.org/netperf/
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
