Hi Alain,

Monitor the internal load of OpenSIPS (via load: class statistics) and see if you really need to add more processes. If you your processing is mostly CPU intensive (no DB, no DNS or other I/Os) and you want to take full advantage of all your CPU resources (if you need them) maybe a x1.5 or x2 factor (between cores and procs) will do it.

Hi all,

I’m using an opensips 2.4 with only dispatcher module.

This server handle around 800 CPAS for 16 000 simultaneous calls.

We run it under VMWARE/Debian with 4 cores and 8 children’s and we have a pic of CPU load to 0,8.

I will upgrade this VM to six cores, but what about number of children’s, do you have a rules to determine the number of children or there is no link with number of core ?

Thanks

Alain
