No problem, I just compiled your stuff to test it, hoping to learn
something.

Yes, with 3 periods, but I didn't use it for recording a large piece yet.
It's a setting I changed one day, but forgot about.
I'll try again after increasing the period size ...

At startup, QjackCtl also doesn't report finding the SSE feature (as it does
with UbuntuStudio on this box) and it reports unlimited  memory locking:
