Should I not allow torrents?

[Preacher with Priors]

I have a Verizo internet service supposed to be 10 to 15 mbs. There is myself connected at the router, then one other conputer and two Android phones. We seem to be having terrible service, so I thought it might be the torrent that one is using to get his movies. Does using a trorent to get a movie take more away frot eh internet service than the usual downloading does. thanlkyou oh and what can some one do to use more than three others, video games>?
