Subject: [linus:master] [btrfs] 574d93fc62: stress-ng.dirdeep.ops_per_sec 25.9% regression
Date: Tue, 14 Jul 2026 15:59:15 +0800 [thread overview]
Message-ID: <202607141457.e5af425c-lkp@intel.com> (raw)
Hello,
kernel test robot noticed a 25.9% regression of stress-ng.dirdeep.ops_per_sec on:
commit: 574d93fc62e2b03ab39c8f92fb44ded89ca6274d ("btrfs: be less aggressive with metadata overcommit when we can do full flushing")
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git master
[still regression on linus/master f105f3631d51e8d7c49bf18ec21b873e4f38e648]
[still regression on linux-next/master 2b763db0c2763d6bf73d7d3e69665222d1f377cf]
testcase: stress-ng
config: x86_64-rhel-9.4
compiler: gcc-14
test machine: 256 threads 2 sockets Intel(R) Xeon(R) 6768P CPU @ 2.4GHz (Granite Rapids) with 64G memory
parameters:
nr_threads: 100%
disk: 1SSD
testtime: 60s
fs: btrfs
test: dirdeep
cpufreq_governor: performance
In addition to that, the commit also has significant impact on the following tests:
+------------------+---------------------------------------------------------+
| testcase: change | stress-ng: stress-ng.link.ops_per_sec 53.7% regression |
| test parameters | cpufreq_governor=performance |
| | disk=1SSD |
| | fs=btrfs |
| | nr_threads=100% |
| | test=link |
| | testtime=60s |
+------------------+---------------------------------------------------------+
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
