Running 22.7.5 on APU4, well configured. Reset to defaults and reconfigured from scratch. Prior config had shaper pipes/queues/rules to address bufferbloat. New config does not have shaper configured (I even checked the config.xml file), but bufferbloat tests still get A+. Puzzled by this, I looked under Firewall/Shaper/Status, and I see the pipes and the queues from the old config are still there. (The rules are blank but the pipes and queues still show the bandwidth settings I had entered in the old config, and they show as processing packets. Which probably explains the excellent bufferbloat tests.)
I have rebooted, even did a cold powerdown, to see if the shaper settings were lurking somehow in memory, but the results remained. So apparently resetting to defaults doesn't clear out everything on disk. Something for the devs to look at, I guess.
Please open an issue on github.
Done. Thanks!
