- display less data in low scales

There are scripts in
svn.openstreetmap.org/applications/rendering/mapnik/utils/
that can help you find out which of your rendering rules take the most
time to compute; these are then prime candidates for either moving to
another zoom level, or creating an index on.
- create generalized geometries
If anyone has found a good solution for generalizing geometries without
sacrificing the "minutely update" option I would be very interested to
hear about that. What I currently do is minutely updates for the
detailed features plus generalized geometries updated weekly but I find
it a bit unsatisfying.
