FWIW, FreeBSD was getting 270MBit/sec one-way UDP and 150MBit one-way TCP out of AR9160/AR9280's late last year. I should re-run those tests again now that I've fixed a bunch of things and see if I've regressed. Those are 2T2R devices w/ a Routerstation Pro (AR7161) as the hostap. At that stage I was maxing out the AR7161 CPU quite badly and filling up all kinds of TX/RX paths, to the point that beacon transmission stopped being reliable. But I haven't really sat down and run performance measurements on MIPS so it's quite possible there's some inefficiencies in FreeBSD that I can work around (to reduce the CPU overhead, I was happy with the throughput.. :) Sujith, would you mind testing out ath9k/openwrt on a DB120 and see if you can get the same results as our internal LSDK builds?
