Also, if the server has multiple processors, use Classic as it will be
able to use them all. Compared to Superserver which can only run
effectively on one processor. And, I have customers that use Classic
on SMP servers with Terminal Services. Also, we do recommend to use
separate servers for both, because Terminal Services can be a CPU,
memory and network hog.
