Subject: [linus:master] [xfs] 2edf06a50f: fsmark.files_per_sec -5.7%
regression
Hello,
kernel test robot noticed a -5.7% regression of fsmark.files_per_sec on:
commit: 2edf06a50f5bbe664283f3c55c480fc013221d70 ("xfs: factor xfs_alloc_vextent_this_ag() for _iterate_ags()")
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git master
testcase: fsmark
test machine: 96 threads 2 sockets Intel(R) Xeon(R) Platinum 8260L CPU @ 2.40GHz (Cascade Lake) with 128G memory
parameters:
iterations: 8
disk: 1SSD
nr_threads: 32
fs: xfs
filesize: 8K
test_size: 50G
sync_method: fsyncBeforeClose
nr_directories: 16d
nr_files_per_directory: 256fpd
cpufreq_governor: performance
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/
In addition to that, the commit also has significant impact on the following tests:
+------------------+----------------------------------------------------------+
| testcase: change | fsmark: fsmark.files_per_sec -3.7% regression |
| test machine | 224 threads 2 sockets (Sapphire Rapids) with 256G memory |
| test parameters | cpufreq_governor=performance |
| | disk=1SSD |
| | filesize=8K |
| | fs=xfs |
| | iterations=8 |
| | nr_directories=16d |
| | nr_files_per_directory=256fpd |
| | nr_threads=32 |

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.
