[mapserver-users] Error While Generating Tiles

Hi,
did you create the spatial index on the geometry column (which I wrongly
called "geom" when it was named "way")?
Example:
CREATE INDEX planter_osm_polygon_sidx on planet_osm_polygon USING GIST(way);
If it still slow, please send:
explain analyze verbose <query>
and the query itself.
I'm expecting a spatial index to speed up the query. But you should also
consider splitting the mapserver layer into more than one, since in the
smaller scales you read a lot of features from the database but then throws
them away when they don't match any class expression. Better to have more
layers with various MINSCALEDENOM/MAXSCALEDENOM and filter the data in the
sql directly. I think the query comes from the layer "area_label".
