Re: But if the Network was so congested..... I agree with CrookShanks. Speed does matter. Some routers allow you to throttle certain services to a maximum bps. For instance, FTP or peer-to-peer protocols. If you have a 50Mbps line and you tell your router to throttle those protocols to 10Mbps, you can use them ALL DAY LONG at maximum speed and the rest of your access will never "feel" it. At the end of the day, you'll have downloaded may GB. Without throttling, you might download the same amount in 1/5 of the time but during that time, anything else you try to do is going to be all but unusable.
Hence, from a network impact perspective, it really is how fast and when and not how much.
