You'll have to profile where the time is exactly spent in MapServer. If it is in pulling data from sources, or in the rendering part itself. There's a OpenGL backend available in recent MapServer versions that could potentially speed up rendering, but it is likely a bit experimental and might need more work. > > Thanks for your advice in advance, > > Visit Hirankitti Ph.D. > > Intelligent Communication and Transportation Lab > King Mongkut's Institute of Technology Ladkrabang > Thailand -- Geospatial professional services http://even.rouault.free.fr/services.html _______________________________________________ mapserver-users mailing list [email protected] http://lists.osgeo.org/mailman/listinfo/mapserver-users
