It says 4500bytes - any ideas? It is the size of a queue for packets in dummynet. It should not be too short so that a couple of packets fit in to give traffic shaper some headroom for its decisions. It should not be too long so that packets are not delayed for too long. In my case 4500 bytes / 3300Kbit/s = 11 ms, which is still good enough for VoIP and NTP. Mark
