Although I would have expected intrinsic delay on the link to crack 100mbits on the rrul test, not 20ms (which is still high), and you only hit 7 on the single threaded tcp up test, based on what I saw in the driver. turn off sqm, stay at 100mbit, let fq_codel ride, try the rrul_50_up test. Also do a capture to see if CE was ever exerted. I do not know why my linksys ac1200 build does not work. I generally suspect it is because my big build server is getting ancient. Can you send me your .config file for openwrt? It would be VERY helpful if you pulled from ceropackages-3.14, and added and built kmod-sched-cake and tc-adv and switched to using the ceropackages feed also for luci-app-sqm and sqm-scripts. There are a couple people here that would probably leap on that! :) add to your feeds.conf src-git https://github.com/dtaht/ceropackages-3.10.git ./scripts feeds update ./scripts feeds install kmod-sched-cake tc-adv kmod-sched-fq_pie edit the .config file to make them modules or installed by default make menuconfig then save make I went through hell trying to to figure out how to switch over to the cero versions of these. If yer doing the builds, I could try hacking the BQL. Maybe. In sweden.
