Why in heck are you doing this! No suprise that ie is so much slower though...
They are also using Comcast, which is a shared internet connection. So speed tests are not really dependent on the browser, it also could be the cable network at the give time of testing. I have seen cable networks go from 24 MBPs a second to 2 or 3 MBPs a second in less than 3-4 minutes.
Do you live in a highly populated area?
