half-duplex will run near line speed in one direction. Try sending in both directions at the same time and you'll get closer to 40% of the link utilization... Also, if you see any collisions you are in half-duplex mode.
You could try connecting the NICs back-to-back with a cross-over cable to take your switch out of the loop?
