Hello Aleksandar,

have a look to this talk from Daniel:

Python is slightly slower because it needs a dynamic object during the cfg 
execution. But with today fast and many CPU cores in a server, I don't think 
that should be an issue in a real-world deployment.

The 30% slower is just for the pure configuration execution. The overall 
capacity of a Kamailio server depends normally more on the I/O performance 
(database, network..) than of CPU capacity. 

So my expectation would be that you see in a normal proxy or registrar 
configuration maybe a few percent more CPU load, in many cases it should be 
not really noticeable. 

Best regards,

Henning
