Are you sure that the data source (wget file or whatever) is RAM resident ? That looks suspiciously like an IDE read limit or similar. I've had non-64 bit athlons running at over 90% of the wire theoretical limit on a pair of intel gigabit cards without much trouble ... but it took some thought to structure the benchmark to make sure (a) the packets contained valid data and (b) other subsystems weren't limiting the flow rate.

I have done similar things over time, and although I have gotten slightly faster speeds (topping out at about 30Mbyte/s), that's about the limit. Same setup but using a 64/66 or better pci slot gets aroudn 100MByte/s throughput (athlon/p3/p4/whatever, that's not important here, pci bus is).
