Super-Seeding is an option within Azureus and some other clients, this option is disabled by default. When enabled, the Super-Seeding service will automaticaly work if there’s less than one complete copy of the file in the swarm (apart from the seeder) and automatically stops when there’s a complete copy of the file in the swarm even if this completed copy is distributed among many leechers… In some FAQs, it’s a good practice to limit the connection to the Super-Seeded file to 3 connections… Let’s start with an example to make it easier: Suppose you have a 10 MB file, this file is composed of pieces, each piece is 1 MB… In normal seeding, you send the leecher the piece it asks for regardless its availability at other peers, you just keep on sending data to whoever asks for it…. In Super-Seeding mode, each peer is assigned a piece, this peer becomes responsible of providing this piece to other peers & tho original seeder won’t send this piece again to any other peer for sometime…. Doing this increases the available pieces to peers, allowing them to download from each other while the original seeder provides them with new pieces…

Furthermore, Azureus gives priority to leechers with higher upload rates. Super-Seeding (accordind to Azureus FAQ): is a feature that allows seeders who are the only seed in the swarm to solely seed pieces that are found nowhere else in the swarm, works something like this: the Super-Seeding client pretends not to be a seed, but pretends to be a peer with an incomplete file. Then the client shares with one peer only, usually the one with the fastest upload to others. And that peer can then share that piece with the swarm. This allows the Super-Seeding client to maximise the efficiency of the upload by only sharing those pieces nobody else has. And because of some other things about the behaviour of Super-Seeding, this function does not work at all well in swarms with one peer and one seed only. So it is only good when the seeder is the only seed, and there are more than 2 peers. Note that Azureus –as a program- considers a completely downloaded file as a seed & a non-completed yet as a peer.
