I have been using the pcengines apu2 boards with good success prior to
now (with ubuntu). I plan to switch one to lede when I get a chance.
I don't recommend using them as a wifi AP, as you get better antennas
out of anything else. Internally I've mostly switched to well-located
ubnt uap-lites (running lede). They don't have any of the
make-wifi-fast fixes as yet, but ac can be dramatically better than n.
I also am mostly liking the tp-link AC2600 - a dual-core arm (on lede)
- again, no make-wifi-fast fixes, but....
I put the edgerouter x sfp in place today on my sonic fiber network.
I'm not sure where the bottlenecks are, but I never get more than
130Mbits down per host I test from (so I suspect they are doing some
interesting shaping there).
I also got some kernel errors when running cake with it with (sigh)
ethernet offloads enabled.
