Hi, I'm testing the activation of more than one processor kernels, at a Dual-Core system. Since I experience nothing when changing the number of kernels, could you please point me to what kind of improvement I should expect, by doing this. Many thanks Bernd.
I hope the gain will be less CPU usage if 1) you have a lot of voices and 2) you have big latency/buffer settings. How much "a lot" and "big" actually means would depend on your hardware. I've tested it with fast-render mostly, where I had one typical midi file taking 15 s to render with one core and 10 s to render with two cores. That was with -z 8192 (if I ran with -z 64, there was no improvement at all).
