Is there a bug if you are on too fast of a connection? When I tried to do the automatic/dual speed test when it ramps up on the different file sizes it gets stuck on the 12MB one and just keeps reloading the page and using gkrellm I saw a constant download speed of 5-6.5 megabytes/sec basically using a ton of bandwidth on the remote server as leaving it going for just 20 seconds would easily eat up 100+ MB of bandwidth. It doesn't seem to do this on my home connection (using the same laptop) and only does it when I am at work, so does it just get stuck in some sort of loop if you are on a fast connection 40+ megabits? I also tested konqueror out (I was using forefox) and it did the same thing.
there was a bug a while back.... but it should be fixed... try doing a 25+MB test and let me know
