For 512-byte packets transmission over 100Mbit takes ~50us by itself, so the OP's target latency is difficult to reach on 100Mbit, even under ideal circumstance

Though I don't think most of the difference the OP found is caused by the linkspeed difference, but the hardware or driver being better after the swap.
