[Ivan Miličević]

Did you install lastest service pack on your MS SQL server? There was a nasty bug with spatial indexing...

Subject: [mapguide-users] sql spatial too slow still?


I'm experiencing huge amounts of lag in SQL Spatial layers .... compared to SDF layers, I've jsut added some code to populate a spatial index, does mapguide make use of such beasts ... can I speed the process up anymore ....
select queries on these tables are completed in under a second, they are by no means large datasets

I've put the following code in place to start producing spatial indexs on my tables.

CREATE SPATIAL INDEX geomIndex ON " & schema & ftable & "(geomcol1) USING GEOMETRY_GRID WITH (BOUNDING_BOX =(473358, 6945073, 553852, 7050461),GRIDS
=(LEVEL_1 = MEDIUM,LEVEL_2 = MEDIUM,LEVEL_3 = MEDIUM,LEVEL_4 = MEDIUM),CELLS_PER_OBJECT = 16, PAD_INDEX  = OFF, SORT_IN_TEMPDB = OFF,DROP_EXISTING = OFF, ALLOW_ROW_LOCKS  = ON, ALLOW_PAGE_LOCKS  = ON)

Is there any other way of improving the speed of the sql spatial server datastore ... (over a minute on rendering the layer isn't going to cut it)
