Have you increased the size of the packets that NFS uses to transfer
information between the hosts? On the client side, use the mount
options "rsize" and "wsize" to increase the read and write packets,
respectively. The Linux default is 1024 bytes which is too small for
performance reasons. For example, Sun systems use 8192 bytes for rsize
and wsize. To be safe, just use 8192.
