Ok, so I've been seeing these commercials for comcast HSI, which I have, touting a speedboost feature that ups your bandwidth to 12 mbit when downloading large files. I barely get 5. I tried to see if it would kick in on a 200mb trailer off apple's site, hosted by akamai, and never got past 650kbps. (5.2mbit). In my mind, that's the apex of download optimization, and comcast is just lying. Anyone with similar experiences? Can't wait for that FiOS 15mbit sustained.
