My Bittorrent program is µtorrent, and I was looking around in it at things I'd never looked at before, like the properties of my torrents. One of the options is a box you can check called 'Initial Seeding'. I seeded Phish 2004-06-21 with that box checked and it finished seeding rather quickly, however, it was a small show. I then seeded MMW 1995-10-14 with Inital Seeding checked and it seems to be seeding out very slowly, it is a much larger show though.
What exactly does the Initial Seeding option do? Should I use it?
