I made many tests changing quantum, queueing for leaf but in no case I could reach the allocated bandwidth with a single download thread. The same limit set on cisco router with traffic-shape, worked fine. Could there be a problem when there are many qdiscs ? Are there many calculations to be done, so the packets get delayed and the TCP transfer rate is lowered.
