help with speed

I have asked about why this is so slow. I read that some people lie about there connection speed. I have a cable modem but sometimes the speed is like at .5 sometimes it is a 5.1. How fast should it be able to go? With other sites it has taken less then a minute to download a song. It takes several minutes here. I am sure it is something I am doing wrong but I do not know what it is. I looked at all the other threads and they are not helping. I do not know what a lot of the stuff means under tools and options. Help
