I use very large period sizes, 1024 or even 2048. The problem of jackd
starting to eat 100% cpu occurs usually when I'm done with my current
work (recording something or fiddling around) and just leave it running
idly. Then when I return to my computer after a few hours jackd sits
there happily eating cpu. It has the side effect of heating my room, but
heating with electricity is expensive and thus I'd rather avoid it ;D

Have fun,
Flo
