Since the speed is primarily based on the other users sharing the files you want, an extensive network is extremely important. When you use BitTorrent, you connect to a network consisting of more than 100 million users worldwide, all uploading and downloading files. Created by the same team that invented the BitTorrent protocol, BitTorrent is an easy-to-use program for downloading large peer-to-peer files.
