TCPWindowSize This value determines the maximum amount of data (in bytes) that can be outstanding on the network at any given time. It can be set to any value from 1 to 65,535 bytes by using the following registry entry: HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Tcpip\Parameters\TcpWindowSize (REG_DWORD) The default for a gigabit interface is set to approximately 65,535 (rounded down to the nearest multiple of full TCP packets), 16,384 for a 100 Mbps link, and 8,192 for all interfaces of lower speeds (for example, modems), again rounded down. Ideally, this value should be set to the product of end-to-end network bandwidth (in bytes/s) and the round-trip delay (in seconds), also referred to as the bandwidth-delay product. This value should be set according to the amount of TCP data expected to be received by the computer. -- Arno Garrels -- To unsubscribe or change your settings for TWSocket mailing list please goto http://lists.elists.org/cgi-bin/mailman/listinfo/twsocket Visit our website at http://www.overbyte.be
