Some hints: - display less data in low scales - add indices for columns you filter on - create generalized geometries - cluster your database on the spatial index The database created by osm2pgsql is not optimized, so rendering will always take a long time if you don't tune it. You should take a look at http://imposm.org if you need on demand rendering.
