I made a few suggestions on that person's gist, as you probably also have downstream bufferbloat as well, which you can fix (on the edgerouter and openwrt) at speeds up to 60mbit on those weak cpus using the user-supplied edgerouter gui for the ingress stuff. The code for doing inbound shaping also is not that much harder, a simple example for that is in the "ingress" section on the gentoo wiki here: http://wiki.gentoo.org/wiki/Traffic_shaping (sqm-scripts in openwrt and other linuxen has the logic for this also built= -in) It is grand to have helped you out a bit. Thx for all the work on http/2!
