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....
Let's go make home routers and wifi faster! With better software!
