comment basic question about mapnik
Mapnik is known for sophisticated cartographic rendering rather than for speed. For dynamic content Mapserver is probably faster. But for static content (like satellite imagery) you can combine Mapnik with TileCache (tilecache.org) or MapProxy (mapproxy.org) which caches static tiles.

Yes, I see, the sum does not work in case there are NULL values. I accordingly updated my answer. That seems to be a shortcoming in the field calculator.
