ill have to fix that.
Oh, and I also realized that CBQ is even worse: it calls microuptime()
on every enqueue *and* every dequeue!
If it really was a bug, people would have noticed, no?

Five years ago I removed a once per packet microuptime call which led

have to do that again. :)
Hey I just realized that hfsc calls microuptime() for every single packet at
dequeue time.
altq_hfsc_dequeue() --> read_machclk() --> microuptime()
Looks like codel won't be slowing hfsc down at least. :)
