Summary: Jack OSX cpu load
Initial Comment:
In Jack mode, Blank empty patch
Toggling Compute Audio on and then off results in cpu load jumping up to ~25% from a nominal 1%. Turn Compute Audio back on, and cpu drops back to nominal 1%.
Tested on 2.4ghz iMac , OS 10.5.6. Pd-0.41.4-extended-rc1

hi - sorry for delay
hmm i don't understand why when Pd is runing in Jack mode and you switch
audio off, why it would revert to a Portaudio state? I that what you are
saying?

Message:
For me, Pd without Jack, i.e. just using coreaudio/portaudio, it will use
25% of my CPU just idling. That's a known issue. With Jack, it goes down
to 5-7% at idle. So my guess is that the first time the 25% spike is
caused by the same think.
Is this causing any problems for you?
