All, I've been lurking on the OpenWRT forum, looking to see when the CC builds for the WRT1900AC stabilized, and they seem to be so (for a very "beta"-ish version of stable).
So I went ahead and loaded up the daily ( CHAOS CALMER (Bleeding Edge, r45715)). After getting Luci and sqm-scripts installed, I did a few baseline tests. Wifi to the MacBook Pro is... broken. 30Mbps vs. 90+ on the stock firmware. iPhone is fine (80-90Mbps download speed from the internet). After some rrul runs, this is what I ended up with: http://www.dslreports.com/speedtest/538967 sqm-scripts are set for: 100Mbps download 10Mbps upload fq_codel ECN no-squash don't ignore Here's a before run, with the stock firmware: http://www.dslreports.com/speedtest/337392 So, unfortunately, it's still leaving 50Mbps on the table. However, if I set the ingress limit higher (130Mbps), buffering is still controlled. Not as well, though. from +5ms to +10ms, with lots of jitter. But it still looks great to the dslreports test: http://www.dslreports.com/speedtest/538990 But the upside? load is practically nil. The WRT1900AC, with it's dual-core processor is more than enough to keep up with this (from a load point of view), but it seems like the bottleneck isn't the raw CPU power (cache?). I'll get a writeup with graphs on the blog tomorrow (I hope). -Aaron
