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).
