I'm not sure what kind of disk backend you have, but you are probably 
thrashing the heads on the disks, making the disks do a lot of seeks, 
burning your performance.  I don't think this is a GFS performance issue 
really.  You could try a memory backed disk with GFS on it, and see if 
the performance falls at all.
