Using differences? You are experiencing the problem from multiple overlaping 
bounding boxes. Try bundling your small bits in a blob that you difference from 
the main object. It's usualy much faster, but you are limited to spheres and 
round capped cylinders.
diference{
	object{Your_Main_Object [Object_modifiers]}
	blob{treshold 0.02
	  Your_Macro}
}
