[Users] OpenSER dimensioning. How many calls/sec can it set up?

[unplug]

Hi ,
I have done some tests in the environment below.
PC1: sipp
PC2: openser+mediaproxy (NAT)
script: nat-mediaproxy.5.0.cfg from configs.GettingStarted.tar.gz

Below is the testing parameter shown in sipp
3 calls / second
concurrent call: 30
Over 30 concurrent calls, message 481 begins to happen.  The CPU usage
of PC2 is almost 90% and then PC2 will hang.

As I expect openser should handle over thousand of calls but there is
a different between my testing.  What I miss to configure for getting
more concurrent call?
