Unless you are using a gigabit ethernet, Open-MPI is noticeably less

I suspect at some point in the future gige will catch-up but for now my
(limited) understanding is that the Open-MPI folks are focusing their
time on higher bandwidth/lower latency fabrics than gige.
This wasn't our experience in our application which runs over gige (see
my previous posting).
