Subject: [sched/fair] 2cfb7a1b03: fsmark.files_per_sec -26.2% regression
Greeting,
FYI, we noticed a -26.2% regression of fsmark.files_per_sec due to commit:
commit: 2cfb7a1b031b0e816af7a6ee0c6ab83b0acdf05a ("sched/fair: Improve consistency of allowed NUMA balance calculations")
https://git.kernel.org/cgit/linux/kernel/git/tip/tip.git sched/core
in testcase: fsmark
on test machine: 192 threads 4 sockets Intel(R) Xeon(R) Platinum 9242 CPU @ 2.30GHz with 192G memory
with following parameters:
iterations: 1x
nr_threads: 64t
disk: 1BRD_48G
fs: ext4
filesize: 4M
test_size: 24G
sync_method: NoSync
cpufreq_governor: performance
ucode: 0x500320a
test-description: The fsmark is a file system benchmark to test synchronous write workloads, for example, mail servers workload.
test-url: https://sourceforge.net/projects/fsmark/
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.
