Greeting,
FYI, we noticed a 125.5% improvement of hackbench.throughput due to commit:
commit: 829c1651e9c4a6f78398d3e67651cef9bb6b42cc ("sched/fair: sanitize vruntime of entity being placed")
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git master
in testcase: hackbench
on test machine: 88 threads 2 sockets Intel(R) Xeon(R) Gold 6238M CPU @ 2.10GHz (Cascade Lake) with 128G memory
with following parameters:
nr_threads: 50%
iterations: 8
mode: process
ipc: pipe
cpufreq_governor: performance
test-description: Hackbench is both a benchmark and a stress test for the Linux kernel scheduler.
test-url: https://github.com/linux-test-project/ltp/blob/master/testcases/kernel/sched/cfs-scheduler/hackbench.c
In addition to that, the commit also has significant impact on the following tests:
+------------------+--------------------------------------------------+
| testcase: change | hackbench: hackbench.throughput -8.1% regression |
| test machine | 104 threads 2 sockets (Skylake) with 192G memory |
| test parameters | cpufreq_governor=performance |
| | ipc=socket |
| | iterations=4 |

cd lkp-tests
sudo bin/lkp install job.yaml # job file is attached in this email
bin/lkp split-job --compatible job.yaml # generate the yaml file for lkp run
sudo bin/lkp run generated-yaml-file
# if come across any failure that blocks the test,
# please remove ~/.lkp and /lkp dir to run from a clean state.
