Hi

We have executed some benchs on gfs2, gfs compared to ext3 and ocfs2
and the results are (just some examples):

* Read on 1 file   :
        quite the same performance

* Write on 1 file :
        
	quite the same performance

* Creation of many many files and repertories :
        gfs2 is 10 times less good than ext3 and ocfs2

* Write of a file tree followed by 4 reading process : 
        gfs and gfs2 : 40 mn
        ocfs2 : 3 mn

Does it seem normal for you ? or is there some hidden tuning somewhere 
to increase
performances when using gfs2 (or gfs)  ?

Thanks a lot.
Regards.
Alain
