  Slightly beside the point, but be aware that unfortunately that's one
of the slowest form of CSG in POV-Ray (ie. one of the most pathological
cases with regard to rendering speed).
  There are several tricks to work around this speed problem and which
give the same result, but I don't remember specifics right now.

  That would depend on the resolution of the rendered image and the size
of the sphere on this image, plus a ton of other things. There's no
specific answer to that question.
