I typically use dslreports.com to test available bandwidth for a connection. I am convinced that my local ISP's have a list of these servers and prioritize traffic to them to obtain better test results. Am I nuts?
Does anyone know of a utility I could run on my web server that would allow me to run a speedtest directly to it from many different computers? This way I could establish a baseline and then more easily see if problems exist on a new connection i am testing?
