Another good way to approach this: start up multiple copies of your process and bind each one to a different core using your OS'es. For FreeBSD, use cpuset. The OS is going to do a better job than any userland code will. Then you need to use an external load balancer to distribute load across your server instances. Extra points for binding a NIC interrupts to a particular CPU.
