Dear Kamailio Developers：

Hi.

I have some questions about kamailio, and want to gain some suggestions from you.

1、The 4 UDP child processes are using system resources(CPU、memory), but they are using only one CPU core(I use 8 core CPU). Why?

2、The ablity of handling the Concurrency is alike, no matter how many UDP child processes I use. Why? And what's the effection of the other UDP child processes?
