One of the reasons why the DL speeds are faster in a uTorrent type program is that there NO throttle on the upload speed in the given app. You're choking your return packets which is causing some of the slow speed. I would imagine adding a preset throttle, say 30%, to the AutoUpdater would greatly increase the DL speed.
@Mekabuser... Yeah I am having the exact same problem. I've noticed that I am missing the AutoUpdater file for some reason though. So I'm re-DL'ing the whole thing in hopes of correction.
@Seraph... Did that Seraph. Still didn't work. Like I said. Missing AutoUpdater.
