Any static base data like roads etc should be served out of a file based provider, you are simply wasting your time with Oracle. MapGuide 2.1 will have caching in place which will improve the reading of the schema, but SDF for example might render in a few seconds, whilst the same data served via oracle takes 4-5 seconds and hits the CPU quite hard. So then with tiling, each screen is broken down into 300px squares, so this means one map view involves say 10-12 requests which all adds up very quickly. 12 blinks isn't that much server load, but 12 x 4s @ heavy CPU will bring the server to it's knees. > > > using the Base Layer Group functionality in MapGuide would mean that > requests beyond the initial request would come from the tiles rather than > from Oracle Yep, tiles are cache and therefore it will bypass oracle completely once the tiled cache is seeded Whether it's tiled or not tiled is purely determined by your mapDefinition. > > > Is there any way around this once my tiles exist? > -- > View this message in context: > http://n2.nabble.com/Generate-map-tiles-from-Oracle-data-tp1336571p1338864.html > Sent from the MapGuide Users mailing list archive at Nabble.com. > > _______________________________________________ > mapguide-users mailing list > [email protected] > http://lists.osgeo.org/mailman/listinfo/mapguide-users > -- Zac Spitzer - http://zacster.blogspot.com (My Blog) +61 405 847 168 _______________________________________________ mapguide-users mailing list [email protected] http://lists.osgeo.org/mailman/listinfo/mapguide-users
