This option is recommended if you 323are serving a lot of data over connections with high bandwidth-delay 324products, such as modems, GigE links, and fast long-haul WANs, and/or 325you have configured your machine to accomodate large TCP windows. In such 326situations, without this option, you may experience high interactive 327latencies or packet loss due to the overloading of intermediate routers 328and switches. Note that bandwidth delay product limiting only effects 329the transmit side of a TCP connection. --- 77 unchanged lines hidden --- | 322unnecessary packets in the network.
