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,
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:
sqm-scripts are set for:
Here's a before run, with the stock firmware:
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:
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
I'll get a writeup with graphs on the blog tomorrow (I hope).
