When you remove pieces with a difference, you get all component's bounding boxes 
to overlap. Each is tested against every bounding boxes, ans each components.

Instead of removing small bits, try making the base shape a little smaller, and 
ADD in an union the small prisms to acheive the same aspect.

Even faster, try using some normals. Chances are that the difference will be 
minimal, barely visible, if you can spot a difference.
