If possible you may want to test in the presence of asymmetric

rewrite tcp window advertisements in the middle of the network -
i.e, traffic in the forward direction flows through the device,
but in the reverse direction does not.
The packeteers detect asymmetric flows and revert to queuing; the
only rate-shape when they can see the whole conversation. Because I
work for a carrier and we have a non-negligible amount of asymmetric
routing (it's normal I say, not argue) when we had packeteers they
would get really upset.
