They used to quote their speeds in ATM frame rates, not in IP speed, and ATM has a lot of overhead. 15%? I wonder if their 40mbps is still quoting frame rates rather than actual IP throughput. Not sure, because 40mbps isn't enough for my home use, so I haven't even talked to them.
Where 40mbps isn't sufficient you mean? A family of 4 with a hell of a lot of video streaming being the primary one, but also not wanting my own Youtube videos to take 3-4 hours to upload 20 minutes. :-)
