    While I do not have any numbers to give you, I can offer you my 
experience on our cluster.  We have used NIS on a 10-node/20-processor 
cluster for a while and have always been able to obtain very good 
performance on our programs.  That is, the overhead of using NIS seems 
trivial on our cluster.  I think that the administrative overhead of 
properly setting up an LDAP directory would be enough to avoid it 
altogether and I can't imagine that the performance is good relative to 
NIS or distributing the password file.  Well, I hope that these comments 
help even though they are not quantitative.
