Hi Junxiao,

Thanks for your sharing, and very appreciated your efforts.

I'm very interested in how your testing env works, could you briefly introduce
it?

Btw, recently, I did a performance testing on both ocfs2 and gfs2 using iozone. The
testing has 3 different cases:
1. local mode: ocfs2 better than gfs2
2. two files mutiple nodes  
3. same file mutiple nodes, for 2 and 3 gfs2 better than ocfs2 generally
Just provide a reference here. I tried to make it as simple as possible,
leaving all formating and mount options as default, and with fixed-size file(2GB)
and buffer(4kb). 

Did you or anyone ever test performance for ocfs2? maybe we can discuss further on
this topic in future;-)

Thanks,
Eric
