Since I use aMule and not the daemon to test the connection issue I have enabled the overhead information.
At first it seems to work when the overhead was very low but it shows something between 0.3 and 3.5 KB. After some hours the upload overhead ist constant 83886.5 KB with little changings. The download overhead still changes between the normal values.
In statistics my upload overhead should be total 3.26 GB and the file request overhead 3.24 GB. The total download overhead is "only" normal 27.34 MB.
