The implementation that is there needs to be further developed to use the spatial index in such queries. Its very doable, but just requires a) someone to fund it or b) a developer to show up and implement it. @ Sjoerd:

Results are a bit disappointing because the performance is very poor (> 60 seconds for a single WFS request). In the SQL 2008 performance monitor GeoServer seems to query the complete DB and does the bbox handling itself. No spatial queries like: select * from MyDB where the_geom.STIntersects(geometry::STGeomFromText('POLYGON ((10 50, 19 59, 19 59,19 59,10 50))', 28992)) = 1 are performed. I only see queries that contain: select a,b,c CAST("the_geom".STSrid as VARCHAR) + ':' "the_geom".STasText() as "the_geom" FROM MyDB Perhaps i'm doing something wrong?

Perhaps i’m doing something wrong?

Finally meeting someone who in simple sentences can point out the essentials needed to make a good DM campaign. This however cannot stand alone; it must be just a part of the total marketing, integrated in the complex world of profitable online marketing. Today we all talk about being effective, targeted and to get optimal results out of the investments in the Internet Market Place and that is not easy; do not tell your prospects that. I think it is often overlooked that DM campaigns must be sharply targeted shoot with rifles not with pellets hoping to hit something. Many clients are impressed when they are told that a DM campaign with 10.000 pellets can result in a high response but what does it help if 50 % or more are useless and the real conversion rate is only 10 %. Does that give a good ROI, no. Better use the principle target narrowly and make more hits. I have with great interest read your blog.

It cannot populate SRS, Max/Min Long, Max/Min Lat. After entering them, cannot see map. It seems to me the SQL Server extension is not working when creating FeatureType.

No WKB, no spatial index support, etc... so I am not all that surprised you are having scalability issues. What is needed is a sponsor for this work. I suggest you send mail to the users list. If enough users are having the same issue it is more likely something will get done about it. Rob:

SQL server has the .STAsBinary ( ) function call on the geometry type. We have been running into serious scalability problems with large vector datasets with geoserver and am wondering if it has do with the lack of the datasources ability to utilize WKB and spatial indexes?
