At 10 Gbps, with 9000 byte packets there's 1.1 million packets/second. Compare that to say, a 56K modem that can handle all of 4 1500 byte packets/second. Als

At 10 Gbps, with 9000 byte packets there's 1.1 million packets/second. Compare that to say, a 56K modem that can handle all of 4 1500 byte packets/second. Also, not only time to retransmit matters, but the amount of power we expend per packet. I think it's ridiculous to have thousands of times more overhead than necessary, and this likely hurts a lot more than the rare retransmission.
