I do know that if you have a long download list that it will take sometime for all of it to download. Actual time depends on you IP connection speed and the source connection speed. also if you are downloading a file and the source computer goes off line then the connection is broken. It will not come back up until that person comes back online. This is why it is best to download items which have mutiple sources. This way if one source is not available there are others which might be.
