I ask because we have a shipload of costly iptables/tc filter stuff only happening in simple.qos (while rural_be will not use any DSCPs besides 0 the filters should still cost a bit CPU). I do not seem to be able to see any additional meta information from the flent files, probably PEBCAK n my side...

simple.qos.
