Logic Pro X Processing Thread Spikes

The logic behind what spikes a single processing thread doesn't seem to be very consistent. I've include a video with issue using some 3rd party plugins which don't take much CPU and run fine and then I add in logic's stock piano sampler and the thing going crazy.


I know I can raise the buffer to make this go away but I want to understand why logic sometimes doesn't handle plugs very well. I thought it was because I was using CPU heavy plugins but when I went to make a list i couldn't make it spike repeatedly. I'm running it under 32 buffer size.


I've had this issue for a long time now. I've tried changing changing interfaces, changing multithreading settings, changing summing, process buffer range, processing threads, turning off all midi devices, .

In your video link you have loaded some instances of different sample players with sample libraries. Maybe it's a problem with too little RAM. 8 GB RAM is pretty low for using sample libraries.

However, you can check this by yourself. While Logic is open, go to Utilities > Activity Monitor and press Memory.
