Speeds vary on amount of bandwidth being used on your local line card (See: Node).
Note: Columbus, OH systems are pumping 512kbps upstream speeds to their customers. You can test your speeds out from speakeasy's local speed-test server in Ohio here.
Most subscribers should be receiving speeds rated between 4.2 - 5Mbps downstream and 330 - 384kbps upstream. You can simply test your speeds using Speakeasy local test servers nationwide - listed here.
Note: Speeds will vary - see below!
Because of the way Cable Internet service works (it's basically a network loop in your neighborhood, and the 'pipe' is shared with everyone on that loop) your speed can vary greatly at different times during the day. If lots of people in your area use RR, and they're all actively using the service, you will not see peak performance. During off-peak hours you are likely to see terrific performance.
In addition, don't be surprised if you have radically different results from different speed tests/test sites. The route that the packets take getting to/from each site will differ, even if they are in the same city or locale. The most reliable way to test your actual speed is to use an "on-network" local RoadRunner speed test. If that's giving you within 90% or so of your configured speed, then the local network, your modem, router (if you have one) and PC are all fine. If "off-network" tests give a radically lower result, then there may be routing issues, network congestion, or all sorts of other things that may be wrong.
