You can easily create a scene in POV that uses only a few 100k of memory 
and takes days to render.

And both are no way measures for the complexity of a scene.  One of the 
most loved (and most hated) things about POV-Ray is that there are 
always multiple ways to accomplish a certain effect.  To find the most 
efficient way is what Poving is all about...
