Lab detail: https://bsdrp.net/documentation/examples/forwarding_performance_lab_of_a_netgate_rcc-ve_4860 My tunning are (same for both test): hw.igb.rxd="2048" (it should be useless now) hw.igb.txd="2048" (it should be useless now) hw.em.rxd="2048" hw.em.txd="2048" hw.igb.rx_process_limit="-1" (It should be useless now too) hw.em.rx_process_limit="-1" dev.igb.2.fc=0 dev.igb.3.fc=0 I can generate profiling data for you: what kind of data do you want ?Received on Wed Jan 11 2017 - 19:42:24 UTC
