I had a quick look over these, both htb+fq_codel egress and bcake egress (both without perf) seem “contaminated" by a periodic process with a period of 50/8 = 6.25 seconds. Is this one of the cyclic probes measuring cpu load or so?
BTW are you using simplest.qos or simple.qos for the htb+fq_codel test (or something unrelated to sqm)? 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...
Best Regards
Sebastian
