Hi, I'd start debugging it by looking at the various debugfs entries in ath9k and try to find some error counters that are "high".
I ported the AR9287 code from ath9k to FreeBSD (minus some code that's never ever called) and performance for me is just dandy. (Or at least was when I last checked.) If disabling encryption helps, there's likely some bugs lying around in encryption/decryption handling which I haven't encountered in FreeBSD. I'd suggest looking at the debugfs entries when there's significant, reproducible packet loss (and not just "it's slow", as that isn't nearly as easily debuggable) to see if you can find counters that increment whenever a packet is dropped. Once you've established that, we can hopefully do some further digging and find what in particular is messed up.
