It means you have a very fast connection. The higher reading is the downstream speed - it measures how rapidly your browser is downloading the code from sites you visit.
The upstream speed, which is always much slower, measures the rate at which your browser sends input data back to the server. When you post in this thread your browser sends your text to our server at 480kbps.
