Subject: ext4/reiser3/btr directory create/read perf
Date: Sun, 27 Sep 2009 14:27:55 +0200 [thread overview]
Message-ID: <a769871e0909270527j5d4a6a51ycb5627ebe94704be@mail.gmail.com> (raw)
Hello,
I executed benchmark which creates and reads 10000 directories.
It is much slower with ext4 than with reiser3 or btrfs.
ext4 without dir_index
void cfs::vdirs_create(): 7754 msec
void cfs::vdirs_read(): 3363 msec
reiser3
void cfs::vdirs_create(): 1173 msec
void cfs::vdirs_read(): 421 msec
btrfs
void cfs::vdirs_create(): 1331 msec
void cfs::vdirs_read(): 567 msec
MD RAID10-f2, 64 kB chunk size
