Firstly fq_codel will always stay very flat relative to your workload
for sparse streamss such as a ping or voip dns or gaming...

It's good stuff.

And, I think the source of your 2.8 second thing is fq_codel's current
reaction time, the non-responsiveness of the udp flooding netanylzer
uses
 and huge default queue depth in openwrt's qos scripts.

Try this:

cero1@snapon:~/src/Cerowrt-3.3.8/package/qos-scripts/files/usr/lib/qos$
git diff tcrules.awk
diff --git a/package/qos-scripts/files/usr/lib/qos/tcrules.awk
