Group: v0.42 Status: Pending

Resolution: None Priority: 5 Private: No Submitted By: boonier (boonier) Assigned to: Nobody/Anonymous (nobody) 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

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?
