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. -- Stephen On 6/15/2010 16:00, Tim Sylvester wrote:
Thanks for the suggestion, that's actually my back-up plan. The key issue is that a single MySQL server will be used, and peak-load on that server can be quite high. By creating multiple instances, I cannot scale the maximum number of sockets high enough meet the requirements. Perhaps on missing 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.
