Probably the reason my renders take a while longer because I leave RayTracing enabled. I haven't tried using depth-mapped shadows - I wish we could have per-object lights in Poser.

One more important factor - shading rate for hair. Best to keep it high via the settings in the object properties (I've been using shading rates of between 5 and 7).
