Subject: [mm/page_alloc] f26b3fa046: netperf.Throughput_Mbps -18.0%
regression
(please be noted we reported
"[mm/page_alloc] 39907a939a: netperf.Throughput_Mbps -18.1% regression"
on
https://lore.kernel.org/all/20220228155733.GF1643@xsang-OptiPlex-9020/
while the commit is on branch.
now we still observe similar regression when it's on mainline, and we also
observe a 13.2% improvement on another netperf subtest.
so report again for information)
Greeting,
FYI, we noticed a -18.0% regression of netperf.Throughput_Mbps due to commit:
commit: f26b3fa046116a7dedcaafe30083402113941451 ("mm/page_alloc: limit number of high-order pages on PCP during bulk free")
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git master
in testcase: netperf
on test machine: 128 threads 2 sockets Intel(R) Xeon(R) Platinum 8358 CPU @ 2.60GHz with 128G memory
with following parameters:
ip: ipv4
runtime: 300s
nr_threads: 1
cluster: cs-localhost
test: UDP_STREAM
cpufreq_governor: performance
ucode: 0xd000331
test-description: Netperf is a benchmark that can be use to measure various aspect of networking performance.
test-url: http://www.netperf.org/netperf/
In addition to that, the commit also has significant impact on the following tests:

If you fix the issue, kindly add following tag
Reported-by: kernel test robot <oliver.sang@...el.com>
Details are as below:
-------------------------------------------------------------------------------------------------->
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.
