VOXL2 has the ability to change the CPU frequency mode. I would like the software I write to run as realtime as possible on the VOXL2, while keeping the CPU as cool as possible. What mode would you suggest in this case, leave it as `auto`, or switch to `perf`? What are the tradeoffs?

Hi Rowan,

There is no one answer, it is entirely dependent on your circumstances. auto will be more conservative than perf. perf is intended to go as fast (and hot) as possible
