Can you eliminate the hub as a variable?

I have seen very similar experiments with multicast packets where the
hub delivered packets out of order, or in a delayed fashion on one port,
but not on the other.
We've tried it with two different hubs (one industrial DIN rail Phoenix
contact model and a standard netgeat one), without changes.
