There is no native support for Spatialite in MapServer, it's all through 
GDAL/OGR.

Subject: [mapserver-users] Does Mapserver utilise Spatialite spatial index 
correctly?

Hi,

GDAL was made to utilise Spatialite spatial index effectively if it exists with 
ticket
http://trac.osgeo.org/gdal/ticket/4212
After this change ogr2ogr with -spat bounding box query is much faster.  
However, when testing MS4W 3.0.4beta1 which comes with GDAL 1.9, the rendering 
speed of Spatialite data with Mapserver is pretty slow. It is evenly slow when 
zoomed out and zoomed in which makes me believe that the spatial index is 
perhaps not used.

Could it be that Mapserver does not utilise the improved method that was 
implemented for GDAL 1.9 when it is doing spatial queries from Spatialite?
