Hacking Windows XP: Speed Up Your Network and Internet Connection: "Depending on the type of network connection you have, you might be able to tweak your connection so that the speed of your Internet, as well as your local area network, will be faster. By hacking the System Registry and editing the TCP/IP parameters, you can fine-tune the values to take advantage of more reliable, faster Internet connections, such as DSL and cable."
