Very nice comprehensive internet speed tester from SourceForge (King of Freeware). Is run from your web browser, uses HTML5, so any modern browser should work. Shows service suggestions, like which internet services you can and shouldn't be using. Netflix, Skype, etc are among the lists. It has a top down overall view of the results, and a more detailed view for those techie nerds like myself who want to understand more in detail what was really tested.
