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
