Basically, triangles can be faster, because they can be put into
one mesh object.

Many objects usually end up slower, because then there needs to
be intersection tests against a large number of bounding boxes.

For comparison, I have a simple scene with two mesh objects
having about 10,000 triangles each (20k total) that renders
in 3 seconds on my 1.9G Athlon

--- include file ---
#declare Thing1 = mesh {
   triangle {...}
   triangle {...}
   ... etc
};
#declare Thing2 = mesh {
   triangle {...}
   triangle {...}
   ... etc
};
--- scene file ---
#include "somefile"
object{Thing1}
object{Thing2}
... and other stuff
