Does anyone else use Xeon processors with hyperthreading enabled?  This has
the effect of doubling the CPUs capacity.  The kernel reports each
hyperthreading cpu as 2 cpus and I believe treats them as such.

If I am running a dual xeon (2 real cpus, 2 virtual cpus) should I be
running 20 MS processes or 10?  100Kmsgs/day running SA and 1 CL virus
scanner.
