This January 2008 Intel whitepaper does a good job of laying out the facts.
Software PBX Performance on Intel Multi-Core Platforms - a Study of Asterisk* http://download.intel.com/design/intarch/papers/318862.pdf It also lead me to Astertest - The Asterisk performance project. I've never seen it referenced before. http://www.astertest.com/ A little real life performance testing at Simon's Saturday Sandbox might be in order. Intel Conclusion Highlights: ...This study showed that for a multi-threaded application such as Asterisk*, which creates a new thread for every incoming call, it is easy to achieve performance increases simply by increasing the number of processor cores; the operating system will schedule the threads appropriately. ...Using several different testing methods, we found that performance of the Asterisk* PBX application increased proportionally as more cores were made available to it. Given that the maximum call capacity on the 8-core system was almost seven times that of the single core case, we can conclude such increases in performance come without significant overhead. In fact, the increases seem to be almost linear as each multi-core configuration was tested.
