link RPCs can be very large (much larger than wsize, for instance).
if you use UDP and your network drops lots of packets, large link
requests will probably require several retransmissions to complete.

enlarge your transport socket buffer size on the client (see FAQ)
and/or try NFS over TCP.  also examine your network to see if it
is clean, and is working optimally.  if your client is attached
via a more slow link than your server, that can be the source of
bursty packet loss.
