µTorrent is one of the most popular BitTorrent clients, with plenty of features such as bandwidth prioritization, RSS auto-downloading, scheduling and Mainline DHT (which is compatible with BitComet, another well-known BitTorrent client), Protocol Encryption joint specification (used also by Azureus 18.104.22.168 and above, BitComet 0.63+) and peer exchange.
µTorrent was written with efficiency in mind. Unlike many torrent clients, it does not hog valuable system resources - typically using less than 6MB of memory, allowing you to use the computer as if it weren't there at all. Additionally, the program itself is contained within a single executable less than 220 KB in size.
Features of µTorrent 3.4:
- Multiple simultaneous downloads - Configurable bandwidth scheduler - Global and per-torrent speed limiting - Quick-resumes interrupted transfers - RSS Downloader - Trackerless support (Mainline DHT)
