Subject: [workqueue/tracing] 83b62687a0: pigz.throughput 4.4% improvement
Greeting,
FYI, we noticed a 4.4% improvement of pigz.throughput due to commit:
commit: 83b62687a05205847d627f29126a8fee3c644335 ("workqueue/tracing: Copy workqueue name to buffer in trace event")
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git master
in testcase: pigz
on test machine: 272 threads Intel(R) Xeon Phi(TM) CPU 7255 @ 1.10GHz with 112G memory
with following parameters:
nr_threads: 100%
blocksize: 128K
cpufreq_governor: performance
ucode: 0x11
test-description: Pigz, which stands for parallel implementation of gzip, is a fully functional replacement for gzip that exploits multiple processors and multiple cores to the hilt when compressing data.
test-url: https://github.com/madler/pigz
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
bin/lkp run compatible-job.yaml
