Subject: Re: Ideas on why using WPA2 encryption speeds up many TCP connections?

I was seeing an un-expectedly bad wifi train rates, so I changed to ath9k-rate-control,
rebooted, and re-ran the tests.  Throughput is much improved.  I really hope it wasn't just
a reboot that fixed it, but too burned out to do more tests today.

I still see better TCP throughput with WPA2 when using 25-200 stations/streams.

For anyone who wants to wade through some big automated reports, see the links
near the top of this page (suggestions for improving those reports are welcome):

(The 600 station reports are a bit dated and were done in a fairly busy
  wifi environment.  We'll re-run those sometime soon-ish.)
