Just first hand experience like yourself. I'm on gigabit duplex too. What's interesting is while I'm downloading my upload far less throttled (I upload at 100mbps sometimes), but when I'm seeding I tend to max at 1 mbps out of the 1000 I'm paying for. Something else is the router AT&T requires will not completely open ports for you. What it does is it is closed for incoming connections that do not hit it multiple times then it opens up, so I appear like my ports are not open on AT&T. But even when I get around that (you can rip the certificates off of the router) AT&T itself limits the connection. If you transfer too much on one port on the backend they will remotely block the port sometimes. (Transferring too much being very little here, around 50MB, maybe even 10MB.) Good news is Comcast does not pull this crap and has fiber internet. Bad news is they start at 2gbps and start at $210 a month in most areas. I'm paying $60 for AT&T gigabit.
