Hmm, you say CAKE and FQ-Codel - so you're not enabling the shaper (that
would be FQ-CoDel+HTB)? An exact config might be useful (or just the
output of tc -s qdisc).
Yeah, I guess I'm also using HTB to get the 900 megabit/s SQM is looking
for.
If I only use FQ_CODEL to get interface speeds my performance is fine.
If you are indeed not shaping, maybe you're hitting the issue fixed by this
commit?

I enabled it just now to get the config.
