Hi, found this website after Google searching about internet speeds. I reside and Hawaii and recently upgraded to TWC's new 300/20 internet. SpeedTest.net shows 300-350mbps to a server located here and Hawaii, and around180-240Mbps to a server in California. This seems fair to me. However, using TestMy's speed test, it shows considerably slower internet speeds. Here is an example: Why is this happening? Thank your very much for your help/input.
