The PostGIS rewrite was more about maintainability than speed. In fact, the new code is a touch slower although probably not significantly so. If you're really trying to crank as much performance out as possible then in many cases shapefiles will win. Convenience should not be overlooked though so why bother with multiple versions of the same data if you can live with a few milleseconds slower.

I have a number of polygon layers that I use on a fairly static basis (political boundaries etc) but I vaccilate between using them from: PostGIS (for convenience - I use them for analysis as well so they are in the database anyway, easy to backup and keep consistent between servers) or from Shapefiles (exported because they were faster to render). Most of them are not overly complex or large, is there still significant benefit to using them from shapefiles, or is it becoming a more closely run race between sources. cheers Ben -- Ben Madin REMOTE INFORMATION t : +61 8 9192 5455 f : +61 8 9192 5535 m : 0448 887 220 Broome WA 6725 b...@remoteinformation.com.au Out here, it pays to know... _______________________________________________ mapserver-users mailing list mapserver-users@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/mapserver-users _______________________________________________ mapserver-users mailing list mapserver-users@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/mapserver-users
