When ANY limit is set it download speeds way below expected speeds.
So when they are a set of torrents that can download at speeds excesses of 85MB's, start getting throttled to around 25MB's when the limit is set too 999MB's.
Here is some images of the bw graph of what I mean when the limit is set too 999MB's.
