If you *really* want to use NIS on your cluster, you should make every
system in the cluster a slave server. Most people just use files. Either
way you can be pretty much assured that you won't see much slowdown.

In most clusters, people are worried about things like MPI or NFS
traffic, not NIS traffic.
