"Overly powerful" is a strong word. Sure it has countless poorly
documented features, but then it fails at even the the most trivial
task at shaping ingress without having to shape your other egress
interface.
Essentially, you have to throw hardware at it.
FreeBSD notably has less of these problems, but neither are all that
viable on large scale throughputs.
