When you go on these speedtest sites you see things like your relative speed expressed in Throughout usually around 970-990 kbps for my basic DSL service. However some sites break the number down expressed in a download speed of 136 kbps. This is consistent with what I get for a average download rate in explorer when downloading from bigger sites like Microsoft, Oracle, etc... What is the difference in these 2 numbers. Is Throughput your max speed, burst rate or something and the other value your true download speed? I hope I'm explaining this properly.
