Tim,
You're correct, though there are a few factors causing me to cautious. The
first is I'm working on new, untested hardware, and given the complexity of the
requirements, I'd rather defer to the knowledge of the list re: performance,
before fully implementing it. The second is that the NAS'es which will
communicate with this RADIUS cluster are known to drop auth requests and issue a
denial if the response is not "quick" enough. Unfortunately this is a 3rd party
managed set of NAS'es, and therefore limited in what I can do.
All that said, I have no concerns about FR, its mainly the DB and the 3rd party
NAS'es.

Thanks for the suggestion, that's actually my back-up plan. The key

something with regard to MySQL optimization, but during testing I found
increasing the
maximum number of sockets was necessary to meet the performance
requirements.
What level of performance do you need - authentication/sec& accounting
packets/sec? FreeRADIUS with MySQL is able to 1,000s of authentications/sec
and reasonably large number of accounting packets/second. You should be able
to tune MySQL to improve the performance.
