Hello [Only registered and activated users can see links. ]
The problem could be the number of people who take the folder, games or whatever, that you downloaded on your computer and therefore can saturate your line. Like someone said I believe (I do not recall his name over, lament)
You yourself can set the number of person minimum and maximum that you allow to come to you to connect to the file, or other games.
Otherwise you can limit the passage of your line directly to your router, which would be no worse either at the same time limit from your torrent software
That is, if its helps a bit
