How to optimize Mac Pro when running only TDM plug-ins.

How would you set CPU usage limit and host processors when your never use any native plug-ins or VI´s, only TDM plug-ins?

I want to optmize my Mac Pro Quad intel for maximum stability and "snappiness".

I am not running any other programs, just PT 10.3.6. with HUI / EUcontrol.

Thanks!
