Greeting,
FYI, we noticed a 113.6% improvement of unixbench.score due to commit:
commit: 6a0b19c0f39a7a7b7fb77d3867a733136ff059a3 ("sched/fair: Consider spare
capacity in find_idlest_group()")
https://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git master
in testcase: unixbench
on test machine: 8 threads Intel(R) Core(TM) i7 CPU 870 @ 2.93GHz with 6G memory
with following parameters:
runtime: 300s
nr_task: 1
test: execl
test-description: UnixBench is the original BYTE UNIX benchmark suite aims to test
performance of Unix-like system.
test-url: https://github.com/kdlucas/byte-unixbench
Details are as below:
-------------------------------------------------------------------------------------------------->
To reproduce:
git clone git://git.kernel.org/pub/scm/linux/kernel/git/wfg/lkp-tests.git
cd lkp-tests
bin/lkp install job.yaml # job file is attached in this email
bin/lkp run job.yaml
