Been playing with the Adaptive QoS feature on my newish AC1900P, which wasn't available on my old N66U. With adaptive QoS on, I'm seeing upload buffer bloat from 800->1000ms. When I use the manual settings in "traditional QoS" mode, it stays 20-100ms (in the "green" using dslreports speedtest). I assume the adaptive QoS does some sort of packet analyzing which might slow some things down, but that seems pretty dramatic. FWIW, I have a 768K upstream connection. I had been using .55 as the upstream limiter on the N66U. Also, when I plug those values in manually with adaptive QoS on, I still get the high buffer bloat; it's only when I go back to "traditional QoS" that it goes away. Is this a big deal?
