µTorrent is a new lightweight BitTorrent protocol
used by µTorrent starting in µTorrent version 2.0 - it makes
incredibly efficient use of network bandwidth while reducing network
problems.
µTorrent works to maximize network throughput
while reducing network latency and congestion - it is designed to slow
itself down when the network is overloaded (when sending and receiving
would only make things worse!) - the result is a win-win of faster
downloads for users with lower network impact for both users and ISPs
µTorrent is user-friendly within a home network, so one computer using µTorrent will not consume the whole network for itself
