RE: NIST Stack BHCA test.

Hi Albert,

We usually test our B2BUA product with 48000 CPH with very good results
and with enough CPU to spare to take us to 60K if we wanted to (on a
dual processor server from Sun). The size of the thread pool will
definitely depend on your application and software architecture. In our
particular case, we found more effective to set the thread pool size to
one, with one SIP listener queuing SIP messages for call processing. We
also found that running this "single-threaded" version of the stack
makes it much more robust because it significantly reduces the chances
of hitting concurrency bugs.

Hope that helps,

Ricardo
