I have a large dataset (7 500 000 polygons) published in a WMS service stored in a PostGIS table (spatial index and attribute index on classitem field). I render this layer between 1 and 100 001. I'm trying to manage my scale by class as Mapfile maxscaledenom <http://mapserver.gis.umn.edu/es/optimization/mapfile.html#layers> to show between 1: 15 000 000 and 1:100 001 the footprint of data (classitem='BBOX') and the data between 1:100 000 and 1:1
Everything working properly. Except for performance. I have tested with a DEBUG 5 to know which element has been evaluated and every element in map has been "checked". Causing this lack of performance. I have also tried union layers but I find it too much time expensive to maintain over a large number of layers. Any hints to solve this problem?
