Most servers of this sort that I have seen tend to be monolithic programs, and only have one process which actually does anything. Multi-processor support will only give you gains in situations where you have lots of separate processes competing for the time on a single processor, as the load could be shared across the multiple processors instead (in which case you run into memory, disk, and other i/o bandwidth limitations instead). As for SMP (Symmetric Multi-Processing) support in FreeBSD, it's in the works, but it isn't in any of the releases to date, and won't be in the next one (2.1.5, which will be out later this week). It'll likely be in 2.2 though, which is due out about the end of the year. If you want to try the current SMP support, and have a Pentium based machine which is capable of supporting multiple processors, then you can talk to the people on the `smp' mailing list (and they'll probably kill me for sending you there, but I forgot the details, so I can't tell you).
