Theoretically, I would like to measure the calls/s.
I am doing some work on this in my "copious free time" - it's derived from kphone and the dissipate stack in its current incarnation, rather than sipsak. I will publish it (GPL) when it is in a fit state. However, I am trying to test more components of the system than simply a cps test (which is really only going to exercise the proxy) - I want to test the effect of lots of registrations, and of the call audio (for instance through media proxy). For "just" a SIP cps test you would probably be best off using something low level (like sipsak) or possibly going down even further, just capturing some packets, doing some sprintf's, and using an ncat type approach. As someone pointed out on a similar thread earlier, the overhead of the test stack/tool is potentially as much a factor in determining capacity as the effect of ser for such a simple test.
The reason I'm not doing this type of test is I suspect in many common deployment environments, straightforward ser cps isn't going to your performance bottleneck but YMMV.
