That's odd. I haven't had any problems with a VDSL connection with 100 down / 11 up. My config is very similar to yours: queue outq on em2 flows 1024 bandwidth 10M max 10M qlimit 1024 default where em2 the underlying interface used by pppoe0. Without queueing I have major problems when utilizing the upstream bandwidth, probably due to dropped ACKs. - todd
