No, not at all. It's related to bounding. Are you using manual
bounding? Is automatic counding on? Most importantly, is union
splitting on? How about removing user bounds (if any)? Are vista and
light buffers on?

What is most probably happening is that for some reason (a bad
combination of settings) POV is checking each ray against all objects
in the scene. As a quick test, try these command line options:

+mb0 +ul +uv +ur +su

If this does not work, read the docs :) especially the chapter about
automatic bounding control and removing user bounds.
