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

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..).

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

Hi Daniel Cardoso,
this depends on certain factors, for example the number of processors/ cores
in your system, the protocols you want to support, and the memory size. More
processed could improve the usage of all your processors, but each process
allocates their own private memory segment, that is not available anymore for
other processes.
In my experience the number of children is not that important for performance,
you may just choose the default size of 8.
Cheers,
Henning

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 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.
