I have not been profiling much on lower end platforms (it's hard, you
can crash a box
pretty easily with the wrong options or sample rates).
While watching the ath10k peak at 150-200mbits, at 99% of cpu in
softirq, I spent a bit
of time profiling various counters and statistics.
for this one (while downloading 12 flows at the same time via flent)
perf record -F 99 -e cpu-clock -ag -- sleep 10
[[31m 67.81%[[m 0.00% ksoftirqd/0 [kernel.kallsyms] [k]
| |[[31m--66.80%-- [[mnet_rx_action

| | |[[31m--41.07%-- [[mag71xx_poll
It appears we're spending 66% of the time in the *ethernet* portion of
I'm going to stop worrying so much about the performance of the new
Let's go make home routers and wifi faster! With better software!
