It all depends on your config. For instance, in my setup I do between 100 to 200 cps with 3 workers. It is important to tune your config based on your requirements and the hardware (mainly number of CPU/cores).

It also depends on your backbone systems. E.g. if you are using DBs or Radius server which respond slow (e.g. hosted in another datacenter causing some RTT delay, then it is better to have more children as otherwise the childrens are blocked waiting for the reponse although the CPU is idle.

Of course the memory consumption increases with the childrens. My default setting is 10. (if the proxy is listining on one UDP socket). If the proxy is listening on several sockets it is better to have less childrens as the children setting is per UDP listening socket.

Hi Henning Westerholt,

Thanks for you reply...

But I would like to know if there is a number that improve the performance...

For example: If come 100 INVITE at the same moment, is there a NUMBER OF CHILDREN that has the best perfomance?

The number of children depends on something?

Thanks

Each process takes care of a request?

yes, each process takes care of a SIP message (request/reply).

Hi Daniel Cardoso,

take a look to the core cookbook in our wiki [1] for more

informations how

...

you can control the number of childrens per protocol (UDP, TCP..).

Cheers,

Henning
