Well, it's not really annoying because i got an hired server and it's damn fast.
But I know somewhone who is running a server as well, but the difference is he's running on Linux.
He has uploads speeds of 120 kbps... so I thought maybe its a setting in my router which isn't right.
But I know more people experience this problem.
Well.. HTTP works really well for me. But it's nice to know it's not because of my settings
Now I don't have to search anymore for another solution!
