While you directed this question to Michael, we have tested this as well in our field trials. We have for example, tested single queue with AQM and looked at p99 latency under load and jitter as well as median & max bitrate for different application flows - then turned on NQB LL and observed the same for the classic and LL queues. What we have found generally is that the bitrates, working latency, and jitter for classic traffic with single queue AQM and dual queue LL is the same; classic queue applications do not experience degradation. At the same time, the NQB flow experiences working latency that approaches idle latency, with consistently low latency.
