Seeds out the files/directory/show once basically. Instead of numerous requests for various pieces, superseeding sends out each piece once...so each piece can then be spread amongst the leechers while the seeder sends out more new pieces. This can speed things up because the seeder doesn't have to seed out the same pieces repeatedly, but it really depends on the number of peers. In practice, it's not always faster.

utorrent does it.
