I got a faster connection, and completely by surprise.
I noticed my downloads the other day were extremely fast; faster than I had ever seen them, and it was with uTorrent. Later, while downloading an via Grabit, I noticed I was maintaining a constant speed right at 800 kB/s when I was always maxing out at 600.
Went and did a speed test, and I guess RoadRunner has improved my connection somehow.
Been getting this good speed for about a week now - hope it continues.
