That depends on the two machines involved.  If either one can not
receive back-to-back packets, then that (lame) machine needs to
use -r=1024 for its NFS mounts.  If the lame machine acts as a
server, then all of its clients need to use -w=1024 as well.

Both of the NetBSD/sun3 Ethernet drivers CAN receive back-to-back
packets, so if you need such flags, blame it on the other end.
