I haven't gone and measured cake recently on low end routers. Certainly less
classes helps it. It would be good if this performance level is true
for the current
implementation with a single queue.

The actual target and quantum are in one of the sysfs aqm files, I believe.

Also I note most of the benefit of the new wifi code is at lower rates
from your AP. Try moving 20 or more feet away....
