ok then it is config issue probably. you should pin it down
to smallest possible number of classes for test (say up to
5 classes) and then use tc -s show class ... to see internal
statistics. Look for classes with small (or negative)
tokens or ctokens - these are in throttling state and are
slowing throughtput - then think if it is ok ..

and as I said before, behavioue changed a bit so that results
can be a bit different a may need tc script changes.
