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. :)
