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).
