Hi all.

    I have problem with performance ocfs2. I just instaled ocfs2 1.4.1 in 2
nodes cluster. I use ocfs2 in mail server. This system has large amount of
small files about 50kB.

Ocfs2 is formated:

>> mkfs.ocfs2 -T mail -N 2 /dev/sdb1

 mkfs.ocfs2 1.4.1
 Cluster stack: classic o2cb
 Overwriting existing ocfs2 partition.
 Proceed (y/N): y
 Filesystem Type of mail
 Filesystem label Block size=4096 (bits=12)
 Cluster size=4096 (bits=12)
 Volume size=220009754624 (53713319 clusters) (53713319 blocks)
 1666 cluster groups (tail covers 7079 clusters, rest cover 32256 clusters)
Journal size=268435456  Initial number of node slots: 2  Creating bitmaps: done
Initializing superblock: done  Writing system files: done  Writing superblock:
done  Writing backup superblock: 4 block(s)  Formatting Journals: done
Formatting slot map: done  Writing lost+found: done
 mkfs.ocfs2 successful

My linux has "load average"  more than 2     (now is load average:
8.47, 6.30, 6.61)

"iostat" is

tps   Blk_read/s   Blk_wrtn/s   Blk_read   Blk_wrtn

1107.00      4619.50       166.75       9239        333

Can you help me somebody?

Thank you
Jan
