Subject: [linus:master] [NFSD] 39d432fc76: fsmark.files_per_sec -100.0%
regression
hi, Chuck Lever,
Fengwei (CCed) helped us review this astonishing finding by fsmark tests,
and doubt below part:
- nfsd4_end_grace(nn);
+ trace_nfsd_end_grace(netns(file));
and confirmed if adding back:
nfsd4_end_grace(nn);
the regression is gone and files_per_sec restore to 61.93.
FYI.
Hello,
kernel test robot noticed a -100.0% regression of fsmark.files_per_sec on:
commit: 39d432fc76301cf0a0c454022117601994ca9397 ("NFSD: trace nfsctl operations")
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git master
testcase: fsmark
test machine: 64 threads 2 sockets Intel(R) Xeon(R) Gold 6346 CPU @ 3.10GHz (Ice Lake) with 256G memory
parameters:
iterations: 1x
nr_threads: 32t
disk: 1SSD
fs: btrfs
fs2: nfsv4
filesize: 16MB
test_size: 20G
sync_method: NoSync
nr_directories: 16d
nr_files_per_directory: 256fpd
cpufreq_governor: performance
In addition to that, the commit also has significant impact on the following tests:
