As I understand it, bin/latency is based on the posix API and demo/altency is based on the Alchemy API. On the BeagleBone black, the former always returns results which are about 10us better than the latter.

Is there any other difference between the two tests? Why do I get different performance? Is the Posix API more performant than the Alchemy one?

Thanks,
Giulio
