rTorrent is a text-based BitTorrent client written in C++,[4] based on the ncurses and libTorrent (not to be confused with libtorrent) libraries for Unix, whose author's goal is "a focus on high performance and good code".[4]

Technical details[edit]

The library differentiates itself from other implementations by transferring data directly between file pages mapped to memory by the mmap() function and the network stack. On high-bandwidth connections, it claims to be able to seed at three times the speed of the official client.[4]

rTorrent packages are available for various Linux distributions and Unix-like systems, and it will compile and run on nearly every POSIX-compliant operating system, such as FreeBSD and macOS.

rTorrent uses the ncurses library and is suitable for use with GNU Screen or Tmux; it uses commands such as Carriage return to load a torrent, after which ^S can be used to start a torrent (where ^ is shorthand for Ctrl key), backspace can be used to automatically start a torrent once it is loaded, making a subsequent issue of ^S unnecessary, ^K for stop, and ^D for pause, or if already paused or stopped, ^D again to delete the torrent.[5] It supports saving of sessions and allows the user to add and remove torrents. It also supports partial downloading of multi-file torrents. In the release of rTorrent-0.7.0 support for BitTorrent protocol encryption was also implemented.[6] PEX, DHT and initial seeding were recently[when?] implemented in rTorrent.

rTorrent can be controlled via XML-RPC over SCGI.
