I noticed the following when downloading a large file: queue tcp_ack parent root on fxp0 bandwidth 2M qlimit 50 [ pkts: 289461 bytes: 15631434 dropped pkts: 16 bytes: 864 ] [ qlength: 0/ 50 ] [ measured: 3660.9 packets/s, 1.58Mb/s ]
While the number of dropped packets is very small and probably insignificant, I would have expected zero dropped packets as little else is competing for the ~12Mbps that's available in the parent queue/circuit. I thought this might be related to qlength, but since this is, apparently, zero during the time of the download I'm not certain what would be causing this. What might I be missing here and how do I resolve (I don't want to set a min here if it can be avoided). FWIW, net.inet.ip.ifq.drops=0. Thanks.
