Really? Please explain then, because the mount_nfs man page
contradicts this...

"Set the read data size to the specified value. It should nor-
mally be a power of 2 greater than or equal to 1024. This should
be used for UDP mounts when the ``fragments dropped due to
timeout'' value is getting large while actively using a mountpoint."

and

"Set the write data size to the specified value. Ditto the comments
w.r.t.
the -r option, but using the ``fragments dropped due to timeout''
value on
the server instead of the client. Note that both the -r and -w
options should
only be used as a last ditch effort at improving performance when
mounting servers
that do not support TCP mounts."
