I have a 1MB/0.25Mb ADSL connection and have an IPFW rule to prioritize outgoing empty acks. If I download a single file with kget at 100 kbytes/s, I see that the rule gets hit at a rate of 50/s: ie a little under 1 empty-ack per incoming packet. I have: net.inet.tcp.delacktime: 100 net.inet.tcp.delayed_ack: 1 which I thought should limit each TCP connection to <=10 empty acks per second
