Well, it's not really by design, but it's the best we can do with current tools, unfortunately. Basically, the problem is the way netperf determines its data output intervals in demo mode: It sends a certain number of bytes, and waits for that to complete before outputting anything. And, well, if the link is really slow, this takes a while, so we don't get a data point until it's done... > If this behavior is expected, let's document the reason.
