[Ocfs2-users] ocfs2 - problem with performance

[Jan Skonc]

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)

 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
