How to measure download speed
There are lots of "speed tests" websites that will measure your download speed, such as the ones provided DSLreports and SpeakEasy.
Or, you can BitTorrent a Linux distro. The advantage is that instead of incoming data from a single site, you get hundreds of streams of incoming data from all over the Internet. The only limitation will be the download link.
I just got a new cable modem line. It's supposed to be 15megs down, but DSLreports said it was only 8mbps down. That could be a limitation with DSLreports, though, so I downloaded CentOS (popular version of Linux) to be sure, and I'm indeed limited to 8mbps down.
The graph of traffic shows that the traffic quickly ramps up and pegs at the maximum. I accidentally had the maximum set to 900-Kbytes/second, I had to up the limit, at which point the traffic averages at 1000-Kbytes/second, or 8-mbps.
