I get mixed results, but they aren't good.  IIRC, apple really changed something about the media access in 10.8, I'll look into that.  And see if my wife will let me install netperf on her laptop (I think it's still running 10.7)

It may be a case of the station aggressively asking to send, and the AP granting instead of sending data to the station that's waiting.

It should be clear in a monitor-mode tcpdump (or a statistical summary of packets).
