Does this machine have a higher (/different) performance shared file 
system such as PVFS or GPFS? We spent some time in november layout out the 
filesystem to be sympathetic to GPFS to help avoid bottlenecks like you 
are seeing here. It would be kinda sad if either it isn't available or you 
aren't using it even though it is available.
