Okay, but that only accounts for 3% and I am seeing around 11%, any
idea what might be accounting for the remaining 8%?

No extra traffic. All machines have a bce0 (not shown in the diagram)
that acts as the management port on a 10.10.0.0 network. Neither NPX8
nor NPX6 has forwarding enabled. But that said NPX3 where the AltQ is
enabled does have ip forwarding enabled. But should not be trying to
route any packets incoming on the bce0, but I will need to confirm. Will
running pfctl before starting iperf for a few seconds be enough? Should
I create a second queue to capture these possible 'extra' packets?
As for the em(4) interfaces, they are all connected directly to each other
using cat 6 cross-over cables, no hub/switch involved.
Where do you see the drop? If you are looking at the end of the pfctl output
that is probably occurring after iperf has finished its run. I have noticed
that the queue bandwidth numbers sharply decline after iperf has finished?

How would you suggest using dummynet? Is it workable for a QoS solution?
Thanks as always,
