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.
