Why is FFMPEG use so much CPU vs native ALSA tools.  For example I am able to record using ALSA device and arecord at a sample rate of 96000 with no issues and using very little CPU. But FFMPEG must be at 22050 to not get buffer xrun errors and it uses 100% of one core of the PI.

Great tool even with this issue.
