Subject: [sched/cfs] e21cf43406: reaim.jobs_per_min 2.5% improvement
Greeting,
FYI, we noticed a 2.5% improvement of reaim.jobs_per_min due to commit:
commit: e21cf43406a190adfcc4bfe592768066fb3aaa9b ("sched/cfs: change initial value of runnable_avg")
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git master
in testcase: reaim
on test machine: 16 threads Intel(R) Xeon(R) E-2278G CPU @ 3.40GHz with 32G memory
with following parameters:
runtime: 300s
nr_task: 100%
test: fserver
cpufreq_governor: performance
ucode: 0xd6
test-description: REAIM is an updated and improved version of AIM 7 benchmark.
test-url: https://sourceforge.net/projects/re-aim-7/
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
