Hi Bansal,
Jan Janak just published some research about the performance of the version 3.0 - it contains some numbers:

With regards to an exact BHCA number, this depends a lot on your configuration complexity, your database setup, logging and DNS speed etc..
In my experience usually Kamailio/ SER is not the bottleneck, normally you've bigger issues (in certain overload situations) getting the calls to the PSTN network through your gateways.
Best regards,
