The “study” by the Germans didn’t measure BT throughput, and that’s the important statistic.

This report only confirms that individual TCP connections are being blocked; it’s being misreported as BitTorrent being blocked. BitTorrent uses dozens of TCP streams so blocking a few of those streams has the effect of slowing down BitTorrent thus “delay”. Furthermore, as TCP streams are broken, BitTorrent will naturally open up more connections automatically within seconds of connections being broken.

They are blocking only at certain CO’s, so you may not be on a Sandvine infected connection. The test’s results show that half the traffic is being blocked, but not blocked totally. Which makes sense if you’ve read into Sandvine and the service they sell. The idea of Sandvine is to corrupt the quality of the traffic. You’ll get your torrent, while still being blocked, and degrading everyone else’s experience.

If the peers are numerous, on bittorrent friendly ISPs, and not total leeches, it wont be a problem. The torrent will live a long and happy life, and no one goes off to complain to the FCC about interference to their paid service. But what if two people in an area with Sandvine hardware installed, do a peer to peer transfer both ways? The result is both clients spinning next to nothing.

The hardware is still installed, and active, all the friggin time. Contrary to what they’ve told the public, and the FCC. Multiple times. Thats the point. Their original story was a lie, its revised story was another lie, what they told the FCC is a lie, and their current spin on these results is just a restated lie. Bullocks to your test, the only result of it is that we know that particular Fedora torrent is healthy. I prefer Debian anyways.

My testing shows that Comcast does not “block” BitTorrent from or to my house.
