What I need to know, from someone who has done it, is 200ms in the ball
park of as fast as Jack can go, or is it worth optimising?

If some one out there has experience using the Jack API, I would love an
answer to that question.

I am using whatever defaults the patchbox distribution uses, I believe. 
I am unsure how to get jack to dump its settings

/usr/bin/jackd -t 2000 -R -P 95 -d alsa -d hw:pisound -r 48000 -p 128 -n
2 -X seq -s -S

It is a wrapper around the C API.  I have looked inside, and that is
what it looks like to me.
