Re:20 Meg Cable Modems Practical Since 1999. (Score 1)

Amen. I was surprised that a mention of Comcast's advertised SpeedBooster technology fell this far down the thread. I can verify that Comcast does boost the speed of downloads (and sometimes it seems even uploads at times) for a brief period of time. I think it's somewhere around the first 20MB or so get a nice boost and then your download tapers down to the speed you should be getting. So technically Comcast is going to get good marks in the speed test because of the brief boost you get, but this boost happens on nearly all downloads where the sending server can manage that speed...
