To see efficiently, there should be some kind of plan, that distributes seeding.
Assign one torrent to a user, dont tell a user to seed many torrents, at a time, that wont help, because he will give lower upload speeds to each torrent. It is better if anyone is assigned to seed a single torrent.
Also if the torrent is huge, assign parts of a torrent to a user.
For example- for the IGCSE torrent, dont tell everyone to download the whole torrent and seed it, that will not help.
Instead we can assign to everyone, such tell someone to seed all maths, someone to seed all science's, someone to seed all commerce, and someone to seed all humanity, languages etc.
That will be more efficient actually.
Imagine everyone starts downloading the whole IGCSE torrent to seed it, that wont help actually.
Users might feel better when seeding smaller parts
