Filesystems speed comparison: ext2, ext3, ext4dev, reiserfs and xfs.

Just a simple test for speed of ext2, ext3, ext4dev, reiserfs and xfs.
I've created a 5G lvm and did mkfs.* to it with all these systems.
lvm> lvcreate -L 5G -n speedtest tvg
mkfs (all default opts)
mount (no opts)
Then make dd if=/dev/zero of=a bs=G count=3
Then make dd if=a of=b

Here are the results:

FS type dd if=/dev/zero of=a speed dd if=a of=b speed
ext2 3221225472 bytes (3.2 GB) copied, 225.283 s, 14.3 MB/s 2047094784 bytes (2.0 GB) copied, 38.4914 s, 53.2 MB/s
ext3 3221225472 bytes (3.2 GB) copied, 248.433 s, 13.0 MB/s 1912479744 bytes (1.9 GB) copied, 52.1087 s, 36.7 MB/s
ext4 3221225472 bytes (3.2 GB) copied, 281.699 s, 11.4 MB/s 1918500864 bytes (1.9 GB) copied, 49.1343 s, 39.0 MB/s
reiserfs 3221225472 bytes (3.2 GB) copied, 248.827 s, 12.9 MB/s 2108379136 bytes (2.1 GB) copied, 62.5061 s, 33.7 MB/s
xfs 3221225472 bytes (3.2 GB) copied, 426.823 s, 7.5 MB/s 2132619264 bytes (2.1 GB) copied, 55.3356 s, 38.5 MB/s

It seems like ext3 is working best with big continious files currently.
Of course this is not a real life situation.
Maybe xfs and reiser will be better for a lot of small files? (reiser has it's glory about that).

Please let me know what you think!
