Dane, Regarding your response:
------------------------------------------------------------------------------------------------- *Good question. You mean WMS vs Tiles rendered on the fly and not cached? I don't know, and its hard to say how you could test that correctly, because most tiled implementations are rendering metatiles. But, I'll certainly keep it in mind for the future.* -------------------------------------------------------------------------------------------------- Actually I mean the performance of WMS tiled rendering vs. how openstreetmap.org does tiled rendering (mod_tile) or does it all come back to mapnik which all of these use to do the rendering. The reason why I ask is that I have heard in the past that WMS rendering is more expensive than mod_tile/openstreetmap.org protocol rendering. I currently have geowebcache on top of apache/ogcserver/mapnik which outputs as tiled WMS and only has to render for non-cached areas and I am thinking about in the future possibly switching to using mod_tile/mapnik which outputs as tiled non-WMS format and I believe also only have to render for non-cached areas. I am wondering if using mod_tile is more efficient than tiled WMS. The reason why I went with ogcserver as tiled WMS was that some of our customers required it to be WMS but that may be changing in the future, so I would have the option to output as tiled non-WMS in the future, but I want to see if it's worth my time to switch over to mod_tile/mapnik. Another reason that I did not try mod_tile/mapnik is that effort for the initial configuration of mod_tile seemed overwhelming, but I noticed that you have set up scripts (link below) to install mapnik, osm2pgsql and mod_tile within Ubuntu linux which appears to make it easier to install mod_tile than the openstreetmap.org documentation. http://bitbucket.org/springmeyer/osm-rendering-workshop/src/c74fa9e14020/installing.rst John Thanks, John
