More often my instrumentation focuses on aggregate performance and iperf throughput numbers suffices for most of that. Occasionally I utilize internal performance measures and/or data provided me by ftrace and related tools. If you're unfamiliar with it, I suggest you look at the Bufferbloat and Make-wifi-fast projects. I suspect that their data and techniques and tools might be of interest to you: https://www.bufferbloat.net/projects/make-wifi-fast/ Also (shameless plug), I'll be discussing WiFi integration debugging techniques and tools at the ELC-NA conference in March. Some of it might be relevant. If you're going, please stop by and say hi. http://sched.co/DXn3 I hope that helps. - Steve -- Steve deRosier Cal-Sierra Consulting LLC https://www.cal-sierra.com/
