Dave,
What is the highest bandwidth that you have been= able to shape with CAKE on the APU2?

Groovy.

I guess if I had any one goal, was that I wanted to have cake to shape
well on the APU2 at a gigabit. That's the highest end "home router= " we
have, although it would be good to get results on things like the turris omnia, also.

I hope to start a round of profiling as to what can be optimized (out)
this weekend. Last I looked the hashing costs dominated.

Pretty sure we're good at 200Mbit there (aside from the ingress bug).
It would be nice to have a test showing blue being useful.

Did you get cpu stats for the below tests?
