Subject: [mm/memcontrol.c] 873f64b791: hackbench.throughput 55.9% improvement
Greeting,
FYI, we noticed a 55.9% improvement of hackbench.throughput due to commit:
commit: 873f64b791a2b43c246e78b7d9fdd64ce909685b ("mm/memcontrol.c: remove the redundant updating of stats_flush_threshold")
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git master
in testcase: hackbench
on test machine: 192 threads 4 sockets Intel(R) Xeon(R) Platinum 9242 CPU @ 2.30GHz with 192G memory
with following parameters:
nr_threads: 100%
iterations: 4
mode: process
ipc: socket
cpufreq_governor: performance
ucode: 0x5003302
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
To reproduce:
git clone https://github.com/intel/lkp-tests.git
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.
