Slow start, sawtooths, the impact of one flow into another, and underlying wifi behaviors are all observable. I do hope you use flent to drive some tests! I am so hopeful for wonderful improvements in the rtt_fair test series as well, and I am dying to hear news of how well the latest babeld is performing. For a live demo of libreqos 1.5 (heimdall branch), please click on https://payne.taht.net and hit "bandwidth test" if one is not already running. It is flent driving the tests (as well as broadband forum's tr-471), one of my favorites is now the tcp_4up_squarewave test because I love seeing the waveforms crash into each other. Libreqos basically leverages ebpf, XDP, cake diffserv4, and a ton of rust to do its magic, it can be configured to transparently bridge a network, and even work to bridge across two vlans. It takes about 20 minutes to compile, but we do have a .deb available for the upcoming 1.4 release which cuts the install time down to 5 minutes. It is too big and too complex to run on openwrt (maybe next year?), and thus we use ubuntu for it, and have it pushing well over 10k subscribers through cake for multiple ISPs now at greater than 13Gbits. We gave a talk about it over here: https://packetpushers.net/podcast/heavy-networking-666-improving-quality-of-experience-with-libreqos/ github here: https://github.com/LibreQoE/LibreQoS
