I have a shiny new Linksys WRT1900ACS to test.
I thought it might be nice to start with some comparisons of factory firmware vs OpenWRT with sqm enabled.
So I built and installed an openwrt trunk but the results were very non-impressive. Rrul test reported mulit-seconds of latency and it was equally non-impressive with sqm enabled or disabled. So I assumed that sqm in trunk on this device must not work yet. Then I wondered how well sqm in trunk was tested and that perhaps its broken for all devices.
My test setup:
Laptop<--1000BaseT-->DUT<--1000baseT-->Server
