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.
Andy.
