Yep with bql. I hadn’t thought about mq before. What my qos setup scripts are

cake instances underneath it?

Only if you want unlimited mode, and birthday problems, and don't have
cpu to burn.

Ok, if I compare the two, latency under load for rrul_be looks “better” (~1-1.5ms instead of ~3ms) with a single “cake unlimited besteffort lan” instance instead of four of them underneath mq.
