I agree. We already have ToS/DiffServ so I would be hesitant to try to
encode some other heuristic into a scheduler. (If your traffic isn't
properly marked you can use some heuristic iptables rules to remark it,
keeping classification orthogonal from scheduling.)
Is it time for prio_fq_codel or wfq_codel? That's what comes to mind
when seeing the BitTorrent vs. VoIP results.
