I see flat RTTs, and a sometimes significant increase in throughputs. Unexpectedly, nfq with GSO throughputs are higher than without nfq at all. ping mean (min-max) RTTs: APU2, nfq without GSO: 80 us -> 82 us APU2, nfq with GSO: 85 us -> 83 us 2011 MBP, nfq without GSO: 13 us -> 14 us 2011 MBP, nfq with GSO: 14 us -> 13 us iperf3 throughputs: APU2, nfq without GSO: 391 -> 415 Mbps APU2, nfq with GSO: 3.35 -> 6.07 Gbps [higher than no nfqueue, 5.55 -> 6.07] 2011 MBP, nfq without GSO: 1.48 Gbps -> 2.73 Gbps 2011 MBP, nfq with GSO: 38.0 Gbps -> 45.5 Gbps [higher than no nfqueue, 39.2 -> 45.5]
