Hi there,

We have two problems with SLD
1) spatial filter (Intersect) is very terrible slow with postgis;
it takes minutes to render hundreds of points! It is better
with shapefile but still not acceptable.
It seems the it reads individual features by oid opening binary
cursor for each feature which is slow.
The intersect feature ends up being converted into a mapserver query
by shape msQueryByShape(map, lp->index, psQueryShape) (where
psQueryShape is the shape passed in the sld. Not sure how to optimize
this. Any suggestions are welcome. Realted subject is discussed inside
bug http://mapserver.gis.umn.edu/bugs/show_bug.cgi?id=1292 and
2) does not work combination of attributes and spatial expressions
(AND logical operator).
Could you send me the sld. I could give it a quick try and see.
thanks in advance,
