  Most clients don't allow this option as it makes the network less efficient. The swarm is efficient due to the fact that users download the pieces randomly and therefore are able to re-seed pieces that a low percentage of other users have.

    Do you know of any research on this? It seems intuitive, but it'd be interesting to look at the numbers, simulated or not.

    It's not random. Clients generally download the rarest pieces first. That way, the torrent is less likely to break when the swarm disappears. If everyone downloads the most popular pieces first, then as the swarm shrinks, clients will soon only have pieces that everyone else has and nobody's downloads would finish.
