I can run an Ookla test in the middle of the night wi= th LibreQoS off for a bit.
From what I recall - without Libre we = see download bloat of 300ms or so. With Libre, it's gone. On waveform w= e see 0ms added bloat each direction for most clients.

And I like the "monitor only" mode idea.
Perha= ps we could create the HTB tree, but just not attach the CAKE qdisc?

One thing Preseem does well= is that their onboarding process includes
"leave it in moni= toring-only mode" for a week, gathering data before you
pull= the switch (although most ISPs I've talked to just pull the switch...)=
It's quite enlightening to see a before/after, even with onl= y FQ_CODEL
as the shaper.

We could proba= bly do something similar with a "monitor only" mode that
doesn't enable any queues (is there a TC equivalent to "dummy&qu= ot; on
FreeBSD?).
