Okay, I guessed as much but wanted to be sure.
I can’t think of any theoretical reason for these results. Cake’s flow isolation should be robust enough to cope transparently with bidirectional traffic in half-duplex mode. As you say, a C2D should easily be able to keep up, and at these modest rates I can even discount PCI bandwidth as a concern. So I might need to try to reproduce it here.
Does the problem go away if you use a wired link with the same setup otherwise? Or is that inconvenient to try? I have some ath9k equipped machines, but they would need to be set up.
