iSpeed

Typically, the classic TCP/IP connection settings will not offer you optimal conditions when you install Windows. The simple changes you get by using iSpeed can increase your connection speed by 60% or more! This translates into faster browsing, shorter downloads, or faster reactions when playing games over the Internet. iSpeed also provides a testing utility and statistical graphs that clearly show you how your connection has become more efficient.

The program also offers a Host file editor to help you reduce connection times to frequently visited sites. In case you don't like the program, it also includes a function to return the registry to its original state.
