It all depend on what is causing the parsing to take lot of time.
If it's calculating data, writing them to a file is the way to go.
If it's due to large images files to be used as image_map, bump_map or
height_fields, try using one or some of the following:
Use another file format as the source. If you use a BMP or TGA, convert it to a
PNG. Smaler files load faster. The time saving from loading compressed files can
be much more importent than the extra time required to process them.
Try using a smaler resolution for the image(s), or one with a smaler colour
range. You don't always need the full resolution or colour depth. It all depends
on your particuliar needs.
Does the parsing start fast, then slows down to a crawl, while you can notice A
LOT of disk activity?
This point to your RAM geting full and the system starting swaping/paging the
data to the disk drive. Install as much RAM as your computer can hold. If you
have a system with an integrated video, try reducing the memory alocated to the
video. POV-Ray don't use the video processor nor the video memory.
