Exponential backoff.  This can be implemented in NFS directly over
UDP for NFSV2 but I don't know of anyone other than Sun that actually
does this.  I find that TCP-based NFS is much faster when going
across a router on networks with a lot of traffic.  Anyway, it is
a win, but only if it works ;-)  It would be nice to know if the
problem is on the client or server side but that requires using
a server with a known good implementation as the server and seeing
if it still is broken.
