Linux NFS is a bottleneck in itself, even with Gigabit Ethernet.  You
can speed up the network, but the current Linux NFS implementation has
limitations which make it five times slower than other forms of file
transfer.  Straight rcp or ftp via Gigabit Ethernet typically reaches
about 25-30 MB/s, while NFS using the same hardware delivers only about
5-6 MB/s.
