Triangles will use more memory, although a single mesh of triangles that is
copied many, many times only uses the amount of memory taken up by the
original.  I think just a few bytes are used to reference each copy.

Generally speaking, traiangles render faster than higher order polynomials
because they behave like a clipped plane.  I think they are only of the
first or second order.

Still, POV-Ray renders polynomials very fast, so it doesn't make so much
difference.

Here's an interesting factoid:  A triangle mesh exported from sPatch will
usually render faster than the same model exported as bezier patches, the
reason being the extra time it takes for POV-Ray to subdivide the patches
into triangles.  For those will memory contraints the bezier patches may be
the better way to go though.
