It's a bit old and for an old version of FreeBSD, but you can use it as a starting point: until you reach the numbers of PPS from those tables, you shouldn't worry :) There are not many SMP benchmarks there, but I think they show that, at least back then, it wasn't worth using on a router. The situation now should be better, but I don't know if anyone's measured it.
