Subject: [xfs] 345a4666a7: vm-scalability.throughput -91.7% regression
(just FYI for the possible performance impact of disabling large folios,
our config, as attached, set default N to XFS_LARGE_FOLIOS)
Greeting,
FYI, we noticed a -91.7% regression of vm-scalability.throughput due to commit:
commit: 345a4666a721a81c343186768cdd95817767195f ("xfs: disable large folios except for developers")
https://git.kernel.org/cgit/linux/kernel/git/djwong/xfs-linux.git xfs-5.20-merge
in testcase: vm-scalability
on test machine: 192 threads 4 sockets Intel(R) Xeon(R) Platinum 9242 CPU @ 2.30GHz with 192G memory
with following parameters:
runtime: 300s
size: 128G
test: truncate-seq
cpufreq_governor: performance
ucode: 0x500320a
test-description: The motivation behind this suite is to exercise functions and regions of the mm/ of the Linux kernel which are of interest to us.
test-url: https://git.kernel.org/cgit/linux/kernel/git/wfg/vm-scalability.git/
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.
