You also have to be careful when generalizing - "Comcast" here locally is actually the old AT&T Broadband network, upgraded many times by Comcast after they purchased it.
But the base technologies installed in each "Comcast" service area are NOT the same. (I can tell for sure that Comcast here locally is using Cisco gear - you can watch the speed throttling behavior and it matches every Cisco QoS box I've ever used. overshoots at first, and then falls back. Comcast around here recently started offering "SpeedBoost" where they're allowing a higher burst of speed for a set period of time PER CONNECTION (TCP, UDP, whatever you are using) and then that connection - just that one - gets throttled. I've tested this on my Comcast line pretty heavily just to know the "expected behavior". I also avoid the public "speed test" sites and use a private server I KNOW is on more than a DS-3 worth of bandwidth for testing purposes.) So. when I see "Comcast is great" or "Comcast sucks" on different online message boards, I always take that with a grain of salt. It's just not the same gear everywhere.

Comcast must cap speeds below what it advertises intentionally, because even distant speed test servers would run higher speeds than what I could get to fellow Comcast users in the same part of town.
