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."
