Subject: [readfile] e83a3e282e: will-it-scale.per_process_ops 18.3%
improvement
Greeting,
FYI, we noticed a 18.3% improvement of will-it-scale.per_process_ops due to commit:
commit: e83a3e282ebeab6bcf3eec024b93fcab0d6e4dc5 ("readfile: implement readfile syscall")
https://git.kernel.org/cgit/linux/kernel/git/gregkh/driver-core.git readfile
in testcase: will-it-scale
on test machine: 192 threads Intel(R) Xeon(R) Platinum 9242 CPU @ 2.30GHz with 192G memory
with following parameters:
nr_task: 50%
mode: process
test: signal1
cpufreq_governor: performance
ucode: 0x5002f01
test-description: Will It Scale takes a testcase and runs it from 1 through to n parallel copies to see if the testcase will scale. It builds both a process and threads based test in order to see any differences between the two.
test-url: https://github.com/antonblanchard/will-it-scale
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
