If it's taking that long to parse, then I guess that you're doing an
awful lot of actual calculation in your POV code. You might consider
performing these calculations only in the first frame, writing the
calculated data out to a file, and coding subsequent frames to read the
file instead of repeating the calculations.

#if (frame_number = initial_frame) 
  . . . do the calculations
  #fopen F "temporary.dat" write
  #write(. . .)
  #fclose F
#else
  // don't do the calculations
  #fopen F "temporary.dat" read
  #read(. . .)
  #fclose F
#end
