Subject: [linus:master] [shmem] a2e459555c: aim9.disk_src.ops_per_sec -19.0% regression
Date: Fri, 8 Sep 2023 13:26:57 +0800 [thread overview]
Message-ID: <202309081306.3ecb3734-oliver.sang@intel.com> (raw)
Hello,
kernel test robot noticed a -19.0% regression of aim9.disk_src.ops_per_sec on:
commit: a2e459555c5f9da3e619b7e47a63f98574dc75f1 ("shmem: stable directory offsets")
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git master
testcase: aim9
test machine: 48 threads 2 sockets Intel(R) Xeon(R) CPU E5-2697 v2 @ 2.70GHz (Ivy Bridge-EP) with 112G memory
parameters:
testtime: 300s
test: disk_src
cpufreq_governor: performance
In addition to that, the commit also has significant impact on the following tests:
+------------------+-------------------------------------------------------------------------------------------------+
| testcase: change | aim9: aim9.disk_src.ops_per_sec -14.6% regression |
| test machine | 48 threads 2 sockets Intel(R) Xeon(R) CPU E5-2697 v2 @ 2.70GHz (Ivy Bridge-EP) with 112G memory |
| test parameters | cpufreq_governor=performance |
| | test=all |
| | testtime=5s |
+------------------+-------------------------------------------------------------------------------------------------+
If you fix the issue in a separate patch/commit (i.e. not just a new version of
the same patch/commit), kindly add following tags
| Reported-by: kernel test robot <oliver.sang@intel.com>
| Closes: https://lore.kernel.org/oe-lkp/202309081306.3ecb3734-oliver.sang@intel.com
