Category: None 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 ---------------------------------------------------------------------- Comment By: Nobody/Anonymous (nobody) Date: 2009-05-18 20:04 Message: Ah, sorry, I misunderstood, I also get similar behavior using Pd version 0.41.4-extended-rc2. Using Jack, I get ~3% CPU when audio is ON and ~8% CPU when audio is OFF. ---------------------------------------------------------------------- Comment By: Nobody/Anonymous (nobody) Date: 2009-05-18 09:56 Message: 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? ---------------------------------------------------------------------- Comment By: Hans-Christoph Steiner (eighthave) Date: 2009-05-14 16:24 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? ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=478070&aid=2791638&group_id=55736 _______________________________________________ Pd-dev mailing list [email protected] http://lists.puredata.info/listinfo/pd-dev
