Do you need to display all at once? I've read that OpenLayers can use different strategies to fetch data. Retrieving everything when the layer is created is of course the simplest one. A more sophisticated solution would be to use a BBOX filter and load data on demand. But this only makes sense if not every feature is required at the same time. _______________________________________________ mapserver-users mailing list mapserver-users@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/mapserver-users
