I'm hoping Sean can make txq !=3D rxq work so that you can have > 8txqs and 4 rxqs. > > > =E2=80=8BThe netgate RCC-VE 4860 is a 4 cores atom C2558E, and I'm using = 2 of the 4 Gigabit Intel i350 ports. Lab detail: https://bsdrp.net/documentation/examples/forwarding_performance_lab_of_a_ne= tgate_rcc-ve_4860 My tunning are (same for both test): hw.igb.rxd=3D"2048" (it should be useless now) hw.igb.txd=3D"2048" (it should be useless now) hw.em.rxd=3D"2048" hw.em.txd=3D"2048" hw.igb.rx_process_limit=3D"-1" (It should be useless now too) hw.em.rx_process_limit=3D"-1" dev.igb.2.fc=3D0 dev.igb.3.fc=3D0 I can generate profiling data for you: what kind of data do you want ?
