[Serusers] SER performance bottleneck ?

[Dragos Vingarzan]

That is something else. But Fang said "registered with only 1-2 users" 
and not just proxy something. So I understood it like Alice, Bob 
registered and then making the same Alice calls Bob thing 3000 
times/second, which will probably end-up as being locked on Bob's lookup 
in the registrar.

My point is: most of the time you have to generate realistic traffic in 
order to see real performance. It is not realistic that Bob gets 3000 
cps terminated to him... having a registrar that would scale properly 
with the number of CPUs is overkill especially as this is not realistic.
