Benefits Of Multiple CPUs With Samba?

PirateBek asks: "We're considering putting in a sizable Linux box to serve our entire campus via Samba. We can save quite a bit of money by going with a fast (PIII-800) single CPU, or spending more for dual slower (PIII-667) CPUs. Is going with two slower CPUs worth the inital dough, or will a faster CPU make up for the added benefit? Does Samba tend to like dual CPUs, or does it really matter? Mind you, we're working under a tight budget, and we want to get the most bang for our buck. Any experience/knowledge in this arena would be quite appreciated."
