[Freeswitch-users] Can FS benefit from multicores processor Linux?

Hi, I need help in best practice using FS. My question is single installation box of FS can gain benefit from the multicore processor and huge memory? Like the performance and capacity of FS will increase from 1 core to 4 cores or even 16 cores? Or if not, can we still gain benefit by using multple VM (each 1 core) in one box? We are talking in Linux of course, using Ubuntu or CentOS. Of cource I am not asking for maximum capacity, because it will be vary between implementation and I know we all hate that question (because what follow after that :) ). Thanks, Donny
