Has anything else changed besides the bond? If your traffic is not sent evenly and burst or cburst aren't big enough to buffer the data until transmit, then it will be dropped reducing your throughput. How are you calculating the transmit rate; is the transmit rate actually 70mbps or is that the tcp send rate, maybe due to retransmission because of tc drops?
