[Sipsak] Re: Questions on sipsak load limitations

[Nils Ohlmeier]

Hello Herman,

as usual the performance of sipsak depends a lot on the host and the network 
environment.
As sipsak does not keep state it does not know anything about ongoing calls. 
Thus the number of "simultaneous" calls is unlimited.
To be honest I never tried to determine the maximum requests per second which 
sipsak is able to generate. I avoid the term "call-rate" intentionally 
because in this case the call-flow is not specified and this can make a big 
difference. In a short test here in my local environment (quite fast: 
gigabit, Ghz CPUs etc.) with the fastest mode, the flood mode without any 
output, I was able to send roughly 74.000 requests per second (which is close 
to the saturation of the Gigabit link).

I hope this helps
  Nils
