Bitmeter is a bandwidth meter, it allows you to visually monitor your internet connection by displaying a scrolling graph that shows your upload and download speed over time. If you spend a lot of time online, especially on file sharing networks such as BitTorrent, Kazaa and eDonkey, then a bandwidth monitor is almost indispensable - giving you real-time updates on how effectively your connection is being used, and alerting you to any problems immediately.
