A) I hope you aren't downloading illegal material, if so, God is punishing you by slow downloads : )
B) In their nature, torrents start slow and speed up over time. This is why they are great for large files. The longer the time the more "seeds" you get connected to. They people who are sending you the data can specify the upload speed. So the people you are getting the data from could have a max upload of 5KB/s. You are connected to 5 people, thats only 25Kb/s
Solution: If its green, then be patient. Best time to do it is overnight. And seriously, don't steal stuff via torrents... you wouln't steal candy from 7-11 would you?
