Best is to use TCP and 64k blocks. And there is a difference
between reading and writing.
With a NetBSD-current (oldish) client and a NetBSD-6.1 server and
a Gigabit link I get:
reading with rsize=64k: ~ 90MB/s
reading with rsize=32k: ~ 60MB/s
writing with wsize=64k: ~ 40MB/s
writing with wsize=32k: ~ 30MB/s
The disk itself gets 110MB/s reading and 90MB/s writing locally
on the NFS server.
Writing via NFS is always slower because even with NFS3 it's
partially synchronous.
