Re: Slow Internet.
VM don't cap or throttle download speeds any more, however they do shape certain traffic (P2P/newsgroups to be specific).
If you're getting that symptom on a speed test, it's a problem. My first bit of advice to you would be to unplug all your devices except the one doing the test, disable wireless and try again.
