What sort of hard disks? What age? What does hdparm -Tt /dev/hd? say on
the appropriate machine?
What else is the NFS server doing?
Les has given you some good advice, but you should also be aware that
* gigabit Ethernet is considerably faster than current hard disks
* hard disk performance (in MB/s) drops as you get closer to the inside
of the disk
* fragmentation (at either end) or multiple small files (although not
in this case) can also add overhead.
Hope this helps,
James.
