hi,
we reported
"[kdave-btrfs-devel:dev/guilherme/temp-fsid-v4] [btrfs] 6c9131ed0d: stress-ng.sync-file.ops_per_sec -44.2% regression"
in
https://lore.kernel.org/all/202309261552.a03eeb4c-oliver.sang@intel.com/
when this commit is:
commit: 6c9131ed0d644324adeeaccd2feeef8d04950b2d ("btrfs: always reserve space for delayed refs when starting transaction")
https://github.com/kdave/btrfs-devel.git dev/guilherme/temp-fsid-v4
we also noticed from
https://lore.kernel.org/all/20230927174741.GB13697@twin.jikos.cz/
the decision is to keep this patch, the performance issue will be addressed
later.
now this commit is in linux-next/master, we captured the regression from fxmark
tests. below fomal report FYI.
Hello,
kernel test robot noticed a -90.4% regression of fxmark.ssd_btrfs_MWUM_72_bufferedio.works/sec on:
commit: 28270e25c69a2c76ea1ed0922095bffb9b9a4f98 ("btrfs: always reserve space for delayed refs when starting transaction")
https://git.kernel.org/cgit/linux/kernel/git/next/linux-next.git master
testcase: fxmark
test machine: 128 threads 2 sockets Intel(R) Xeon(R) Platinum 8358 CPU @ 2.60GHz (Ice Lake) with 128G memory
parameters:
disk: 1SSD
media: ssd
test: MWUM
fstype: btrfs
directio: bufferedio
cpufreq_governor: performance
In addition to that, the commit also has significant impact on the following tests:
