Huh, that's really bad. I haven't done any throughput tests for months,
but when I did I was able to easily get over 500 Mbps with iperf TCP OTA
tests (can't remember if TX or RX was better). This was on an x86

When running throughput tests make sure to disable all possible kernel
debugging you have. Starting from CONFIG_ATH10K_DEBUG all the way to
slub debugging etc.
