"that depends" - it is highly dependent on the type of disk activity you 
are performing.

There are various reviews of both FSes circulating.

Personal observation: GFS and GFS2 currently have utterly rotten 
performance for activities involving many small files, such as NFS 
exporting /home via NFS sync mounts. They also fails miserably if there 
are a lot of files in a single directory (more than 5-700, with things 
getting unusable beyond about 1500 files)

I have not used OCFS2 in production environments, so I cannot comment on 
its performance in these scenarios.
