When I did I promised a more thorough performance evaluation of it. This took a bit longer to get done than I had anticipated, but I have now put up a blog post with some pretty graphs. The post also explains the background of the 802.11 performance anomaly to those not familiar with it; feel free to skip to the results if you are already familiar with it.
