Sure you get nearly your line rate on the line from your house to your DSLAM. Once you get to the DSLAM, you are mixing with all the others users traffic. Some DSL providers cap your guaranteed bandwidth at about 10kbps.

Cable modems are notorious for failing to deliver the full bandwidth the subscriber is paying for. In many places customers end up getting 33Kbbps or less on a regular basis. The available bandwidth tends to fluctuate frequently. In contrast, many (if not most) DSL systems will provide a constant bandwidth close to the maximum rate the customer is paying for. Most DSL providers will cap the available CONTINUOUS rate to around 540Kbps for a 650Kbps connection (as an example). All DSL providers will allow the rate to momentarily spike to the full speed the customer is paying for. A small number of DSL providers allow the full bandwidth to be used all the time.
