I can give my experiences here. I have a very slow server that I use for client demos, and I very often hit this exact same issue (my OpenLayers/MapServer WMS/WFS application takes very long to load initially, then zooms along). In my case, the long initial load is always due to the large lib/OpenLayers.js file; I solve this by generating an 'OpenLayers-lite.js' file (through the instructions at http://docs.openlayers.org/library/deploying.html). I hope that helps someone along the way. Have a nice weekend all. -jeff -- Jeff McKenna MapServer Consulting and Training Services http://www.gatewaygeomatics.com/ _______________________________________________ mapserver-users mailing list [email protected] http://lists.osgeo.org/mailman/listinfo/mapserver-users
