How did you come up with those numbers? This sounds more like POV-Ray is
actually rendering the image again. Did you check the message output? It
takes only seconds to continue a render! What version are you using, and
what is your setup? You are not by any chance trying to resume a render over
a slow connection like an NFS share or something like that?
