[mm/page_alloc] 39907a939a: netperf.Throughput_Mbps -18.1% regression
by kernel test robot
Greeting,
FYI, we noticed a -18.1% regression of netperf.Throughput_Mbps due to commit:
commit: 39907a939a34033eeea112751f0e4330628d3a9a ("mm/page_alloc: Limit number of high-order pages on PCP during bulk free")
https://git.kernel.org/cgit/linux/kernel/git/mel/linux.git mm-pcpllist-v1r2
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.

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.

[mm/munlock] 07ca760673: stress-ng.tmpfs.ops_per_sec 24.4% improvement
by kernel test robot
Greeting,
FYI, we noticed a 24.4% improvement of stress-ng.tmpfs.ops_per_sec due to commit:
commit: 07ca760673088f262da57ff42c15558688565aa2 ("mm/munlock: maintain page->mlock_count while unevictable")
https://git.kernel.org/cgit/linux/kernel/git/next/linux-next.git master
in testcase: stress-ng
on test machine: 128 threads 2 sockets Intel(R) Xeon(R) Platinum 8358 CPU @ 2.60GHz with 128G memory
with following parameters:
nr_threads: 100%
testtime: 60s
class: memory
test: tmpfs
cpufreq_governor: performance
ucode: 0xd000331
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.
