As far as I can tell, all (most/many) of the flent scripts basically have netperf TCP/IP streams running full tilt.

I guess put another way, how effective are the anti-bufferbloat methods at reducing latency on a moderately loaded link?

In terms of WiFi, do I need to run a link at 90+ airtime congestion to see OFDMA work it's magic? Or would the lack of available airtime hinder it working?
