Mapserver/PostGIS performance

[Rhys Ickeringill]

Hi List,

When using MapServer to rasterise a map which references PostGIS layers,
does anyone know if:

(1) there a performance impact if the generic geometry type of the layer is
set to "GEOMERY" rather than using one of the more specific geometry types
(eg. LINESTRING, POLYGON, POINT)?

(2) there a performance impact if the geometry type of a layer of polygons
is set to MULTIPOLYGON rather than using the more specific POLYGON type ?

I have a number of big layers which are 99% of one geometry type, but with a
sprinkling of others. Hence I am wondering whether it is worth huting out
and removing the other 1%, or whether it's not worth it and I should just
use a more generic geometry type description...


Thanks
