And when I say that, I mean it. HTB eats all the cpu, leaving nothing for wifi , wifi crypto, the web interface, etc, at these rates. I have long been looking for something more efficient than htb without much luck. So assuming your downstream bloat isn't "bad", and you stick with cero on this interface, I'd disable the downstream rate limiter entirely (set it to 0), and just use sqm on the upstream. It is increasingly hard to hit the higher bandwidth limits with normal traffic.
