Splendid Idea - As of yet, all test cases indeed were the same two physical
machines, however if the client is a FBSD7 instead of the kubuntu one,
comparable results are showing, so i suspect the server (FBSD7) to be the
source of the oddness. I will try your suggestion as soon as the
FBSD(Notebook) is back, should be tonight. Furthermore, there is a FBSD
Dualboot on the kubuntu machine that i will test later to see if it shows the
Funnily enough, if the second transfer is a very small-bandwidth one, like
watching a movie instead of transferring it, the positive effect on the first
transfer is also a LOT smaller than with a concurrent high-bandwidth access.
