Indeed. As a point of reference, an AR6004 device I have on my desk
(which is a/b/g/n, no ac), built into a custom SBC, I can normally get
iperf runs of >35 Mbits/sec.  So, in short, that run is showing
there's an issue. I don't have your device so I can't really help out
much more than that, but in the next week or so I'll try to look at
the patches and see if something pops to my eye.
