Subject: [linus:master] [ext4] 7ac67301e8: aim7.jobs-per-min 22.9%
regression
Hello,
kernel test robot noticed a 22.9% regression of aim7.jobs-per-min on:
commit: 7ac67301e82f02b77a5c8e7377a1f414ef108b84 ("ext4: enable large folio for regular file")
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git master
[test failed on linux-next/master 3a83b350b5be4b4f6bd895eecf9a92080200ee5d]
testcase: aim7
config: x86_64-rhel-9.4
compiler: gcc-12
test machine: 96 threads 2 sockets Intel(R) Xeon(R) Platinum 8260L CPU @ 2.40GHz (Cascade Lake) with 128G memory
parameters:
disk: 4BRD_12G
md: RAID0
fs: ext4
test: creat-clo
load: 1000
cpufreq_governor: performance
In addition to that, the commit also has significant impact on the following tests:
+------------------+----------------------------------------------------------------------------------------------------+
| testcase: change | filebench: filebench.sum_operations/s 13.9% improvement |
| test machine | 192 threads 4 sockets Intel(R) Xeon(R) Platinum 9242 CPU @ 2.30GHz (Cascade Lake) with 176G memory |
| test parameters | cpufreq_governor=performance |
| | disk=1SSD |
| | fs=ext4 |
| | test=randomread.f |
+------------------+----------------------------------------------------------------------------------------------------+
