Poor PE4600 NFS performance

Yes, the PERC-3 controller is configured and enabled. We are getting
60-90 MB/sec read rates of the RAID-5 array. Also, plain TCP
communication occurs at about 67-85 MB/sec depending upon the particular
gigabit NIC in the other machine. These two benchmarks seem to imply
that we should be getting much better NFS read performance.
