I have seen some DBAs try to normalize data beyond belief. It is fine to have a few lookup tables for common values, but if have a 10,000 records and 5,000 possible values in a column, don't bother with a lookup table. Just put the values directly in the table. My point is just be sensible.

What do you mean by "Tables structured correctly"?

Actually, it is possible. I found performance gains by using SQL Server 2008. The keys to success are making sure you have the tables structured correctly and properly indexed. If you are using themes, then make multiple connections to the data and use SQL queries instead. I will agree that SDF is faster than SHP.

I am not sure it is possible...I get the same results as far as speed and the different data connections you described.

I was trying to load data from SQL Server 2008 using the Osgeo FDO Provider
for SQL Server Spatial data connection in MapGuide Enterprise 2010. It
seems slower than shapefiles when previewing in MapGuide Studio. I find SDF
format to be the fastest of the 3 formats.
I originally had a shapefile about 100 MB in size. The loading time in
MapGuide:
SQL Server - 41 seconds
Shapefile - 30 seconds
SDF - 15 seconds
Any ideas how to make loading from SQL Server data faster with MapGuide?
Does it have something to do with FDO provider?
