POV is re-parsing the whole thing for each frame.

There seems to be some confusion in your post about whether the problem
is with the parse time or the render time. Look at the stats to see if
parsing or rendering is taking too long, and change your code to improve
the efficiency in that area.

Also check to see if you are running short of memory. 150Mb of geometry
data is going to expand into a huge amount of parsed geometry. Once POV
requires so much memory that the system starts shuffling virtual memory,
the render times go through the roof.
