Hi

I would like to have some rough estimate of the registrar performance (with DB).

If there is no figure available, does it make sense to use call performance benchmark like this one
http://www.transnexus.com/White%20Papers/OpenSER_RTPproxy_test.htm
and extrapolate to registrar performances ?
eg. can I say that the SIP REGISTRAR is able to handle >600 registrations per second in the case of TransNexus testbed ?

Pascal
