Well, as Jeff said, the only safe way to run NFS servers for ROMIO is
by disabling all caching, which in turn will dramatically slow down
performance.

Since NFS is performing so slowly for you, I'd suggest taking this
opportunity to deploy a parallel file system. PVFS, Lustre, or GPFS
might make fine choices.
