That's exactly the point. With large frames, you can get high rates of traffic. With smaller frames, rates drop quickly. We're using FreeBSD (with Zebra) as core routers for about 80Mbit of traffic to 3 main providers and about 25 local peers. We're facing the point where we have to decide to invest a little in the platform or ditch it for some name-brand gear. Much of the recent hacking on FreeBSD has been done in house and we recently hired another coder with kernel expertise to hack on the code. Of particular embarrasment is that FreeBSD produces source quench packets when acting as a router. Aparently an RFC made this a bad thing(tm) some time ago. Anyways... the average packet size at the core router is much smaller than 1500 with much of the traffic being in the "tiny" <100 byte category.
