	[SM] Ah, I see. But just for our discussion here, how much (potential) capacity did you need to treade in for decent responsiveness?

	[SM] Good point... especially for upload tests, I occasionally see numbers which I know for a fact to be impossible (abovre the gross capacity of my access link) and I wonder whether all tests actually do proper reporting of the grand average capacity numbers. This should not be rocket science: take the start time of the first maesasurement flow and the end time of the last measurement flow and divide the total number of payload bytes trasferred by the total time this took.
