Deluge is an open-source, cross-platform BitTorrent client for Windows, Linux, and Mac OS X. It uses libtorrent as its backend. It has a plug-in system and supports all the features you’d expect: BitTorrent encryption, DHT, peer exchange, magnet URLs, UPnP, RSS, bandwidth scheduling, per-torrent speed limits, a web interface, and more.


One of my friend suggested me qBittorrent. In his view this is also a best alternative for uTorrent.This application have some way have the similar interference  what uTorrent and BitTorrent have.In my view both Deluge and this have the same performance.
