Shaping the uplink only still helps a lot.

The fastest-looking thing I've played with of late is the netgear x4.
It's dynamic QoS feature
is basically fq_codel, near as I can tell. I'll try pushing it to
120Mbit this week.

I do not have a high impression of it's overall firmware quality, and
haven't seen the gpl drop yet.

Aside from that, there's always x86.
