In Windows XP some issues with poor uplink and downlink throughput can be resolved by manually adjusting the TCP window size This setting is found in the registry under HKEY_LOCAL_MACHINE SYSTEM CurrentControlSet Services Tcpip Parameters The ideal TCP window size for a given maximum bit rate is dependent on the network delay Here is an example showing how to do the calculation Suppose that Maximum bit rate 3 6 Mbit s Network delay 500 ms Maximum Segment Size MSS Maximum Transmission Unit MTU header size 1500 40 1460 bytes Then Bandwidth delay product BDP 3 6 10 bit s 500 10 s 1800000 bits or 1800000 8 225000 bytes Unscaled TCP Receive Window RWIN floor Max Buffer Size MSS floor 65535 1460 44 That is 44 segments totaling 44 1460 64240 bytes is a good configuration for a connection with MTU 1500 and MSS 1460 To obtain the optimum scaled RWIN multiply the unscaled RWIN by 2 repeatedly until the BDP is reached 64240 2 128480 lt BDP 128480 2 256960 gt BDP Thus given the above assumptions the optimum RWIN TCP Receive Window is 256960 bytes You will need to restart Networking in Windows XP for the new TCP window size to take effect Windows Vista and Windows 7 have a function for automatic tuning of TCP settings Check whether that function is enabled as follows 1 Open a Command Prompt using the Run As Administrator option right click the Com
