Adrian, That is a good question and I agree with your point. However, what I am trying to understand is how efficiently OpenSIPS is using the hardware resources available and if its performance can be optimized. I am using a basic configuration for my tests (stateless server, no authentication, no DNS). In a more realistic scenario, the additional functionality will reduce proxy's performance considerably. I am interested in the performance with authentication. Given SIP's flexibility, I can think of scenarios where more SIP messages are authenticated (not only INVITEs and REGISTERs), and where more services require authentication (i.e., IM, presence). In this scenario, if the performance of the proxy is not good enough, an option could be to upgrade the hardware or add load balancing tools. I would like to know if we can do better without adding more hardware or components. Also, having extra-performance is a good thing, specially in situations when unexpected loads happens (i.e., flash crowds, emergencies, DoS attacks). I will appreciate any more thoughts or comments regarding this subject. Thanks, Italo _______________________________________________ Users mailing list [email protected] http://lists.opensips.org/cgi-bin/mailman/listinfo/users
