OpenSCAD's performance only scales with the clock speed of a single CPU core. On any sufficiently complex composition, the underlying geometry engine will eventually either slow to a crawl due to combinatorial node visits or fail to render due to opaque assertion failures. This is not the basket to put your eggs in for professional modeling. It will let you down and there is no clear path to making it better any time soon.
