Subject: [linus:master] [btrfs] c87c299776: sysbench-fileio.write_operations/s 14.7% regression
Date: Wed, 5 Feb 2025 13:43:25 +0800 [thread overview]
Message-ID: <202501311641.4c5b6a89-lkp@intel.com> (raw)
hi,
we reported
"[linus:master] [btrfs] c87c299776: iozone.average_KBps 18.5% regression"
in
https://lore.kernel.org/all/202411302252.67284087-lkp@intel.com/
now we got more performance results for this commit. just FYI.
Hello,
kernel test robot noticed a 14.7% regression of sysbench-fileio.write_operations/s on:
commit: c87c299776e4d75bcc5559203ae2c37dc0396d80 ("btrfs: make buffered write to copy one page a time")
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git master
[still regression on linus/master 72deda0abee6e705ae71a93f69f55e33be5bca5c]
