Use this registry item to set the size in bytes of TCP's Winsock buffer. Using a large value may increase the throughput of connections where the delay is large in relation to the bandwidth. This includes Internet, ISDN, RAS, dial-up networking, WAN and satellite connections.

For example, if the delay between two end points is 500 msec (.5 sec), the default throughput will be limited to 8K / .5 sec = 16K/sec. By increasing the value to its maximum setting, the theoretical throughput will be 65535 / .5 sec = 128K/sec.

Disclaimer: Modifying the registry can cause serious problems that may require you to reinstall your operating system. We cannot guarantee that problems resulting from modifications to the registry can be solved. Use the information provided at your own risk.
