there is a big overhead in using oracle, basically FDO involves getting a WKT type datatype out of oracle spatial datatype which is quite an overhead.
if you try using the oracle WKT functions via sql you will see a similar conversion overhead Your better off moving static data into SDF's to avoid that conversion every time you make a map or at least make use of tiled maps for base oracle layers. That said, you shouldn't be having the problems your seeing... generalising your data might help... what's the tolerance of your data? depending on what your doingthere's not much point in making maps at street level with data that is down to say 5mm if you get my drift, when 1m would suffice how does it perform with just a single oracle layer? can you isolate the problem down a bit? z On Tue, Apr 15, 2008 at 9:04 PM, Marius_360 <[EMAIL PROTECTED]> wrote: > > Hi All > > My map runs on Windows Server 2003, Oracle 10Gr2, Mapguide Opensource 2 and > the latest King providers but I am encountering problems when zooming in a > few times.
