Internally the rPI is a ver awkward beast: the CPU is connected to a
GPU, and the GPU is connected to the GPIOs... so lots of jitter and latency.
It was designed to be a video decoder... the CPU is there for testing
and housekeeping. It works, surelly, but it´s not designed to have low
latency and jitter.

In terms of performance, ARM based credit card sized computers do well if
you can get the PPS to the general purpose I/O pin that interrupts on an

What/why can't the Pi do? I have one handy that is processing a PPS on a
GPIO pin.
David Taylor has a web page with all the fine print on how to set it up.
(Thanks.)
