If your switch supports it you'll probably want to enable jumbo frames, mtu,
on the server, switch and the clients. It's probably also a good idea to set
your rsize ,wsize mount options to 32768. The wsize and rsize options
specify the size of the chunks of data that the client and server pass back
and forth to each other. Obviously, the more data you can transfer in one go
the better. Depending on the needs of the applications you might get a bit
of a performance boost by disabling access time updates on the nfs server.

Another performance booster for writes at the expense of possible data
corruption if a reboot were to occur during writes is the use of the async
option. This allows the server to tell the client everything was
successfully written before it actually all has.
