Re: Keynote/Boardwatch Internet Backbone Index A better test!!!
Jack, Your study proves that if a user connects to the network, he can expect better response time surfing www.uu.net than he could expect from surfing www.mci.com. While this is interesting, this has little or nothing to do with the network performance of either uu.net or mci.net. If your goal is to report on the performance that a dedicated user might expect from uu.net or mci.net, become a customer of either network and test the response time to the top 100 web sites in the world. Better yet, use your publication to print measurement software that your readers might use to test each network and report the results to you. If I had published the article that you just published, I don't know if I could backpeddle fast enough. Your method is flawed and your results are misleading.
