A tool for assessing WiFi/WLAN network security. Overall profile runs on all cores and overall not long running.
Topdown profile shows a high retirement rate and some backend stalls. The frontend stalls are very low as are speculation misses.
AMD metrics show very little floating point, and very little L2 access. Branches are also extremely low and also branch misprediction. Backend stalls are CPU and not memory.

Intel metrics have slight differences, more of the backend stalls are tagged as memory. The L2 access is still low. This report now has L1/L2/L3/dram metrics and almost all is with L1 and not further in the memory hierarchy.
