OK, but DNS queries are short (less than 1 KB).  You probably know much
better than me (I also work with scientific computing, but it's been only 4
years) that you can't expect terrific performance with thousands of messages
per second -- this will always be your bottleneck.

As such, I believe it's unfair (and imprecise) to use DNS performance results
for a group communication (MPI) environment comparison.  I had good
experiences with MPI + FreeBSD, although don't have numbers to prove.

Regards.  :)
