There must be something :-) One thing I thought of, if you are getting any congestion/packet loss on the ftp upload, then you would expect results more like you see. I would take a closer look at what is happening to the upload connection. You could get an idea of whether you are dropping by doing some netstat -s | grep retrans on the box running the upload. You could also do a tcpdump to look at what window the server is letting you use / see drops. Looking at backlogs with tc -s class ... should show the FTP class as backloged all the time - if it's empty(not there) sometimes then that's another sign that something else is limiting it.
