Convolution is slow on mac os

Edit: Ok now I messed my post up. :smiley: This was about Convolution DSP Of JUCE being slow on Mac Os but turned out to be my mistake.

Did you test with the exact same IRs? Did you test with a release build on both operating systems? How did you measure the CPU load? Did you take into account Windows and macOs OS CPU meters show the CPU load differently on multicore computers?
