Tairent is a minimalistic BitTorrent client for Linux servers. This means that it has no GUI, TUI, or CLI. Instead, it provides an effective way for serving large files using the BitTorrent protocol. One of the key features is that Tairent tries to minimize data copying in memory by using mmap for mapping files into memory and then sending them directly to the peer.
