Hi all One of the underlying datasets in my P.Mapper app is a model grid (many thousand cells) in a shapefile. The data displays nice and quick when just viewing, but if I allow the user to select say 5000 cells (using the select by rectangle tool or even the seach tool) it is very (extremely) slow to redraw with the highlighted cells. Doing the same task in a very old ArcGIS server web app was much quicker (admittedly the data was in SDE/MS SQL). So my question is what is the best way to improve performance? Does using a shapefile just not cut it when selecting so much data? Has anyone got P.Mapper to work with a mapfile containing a layer where the data is within a MS SQL 2005 db with the MSSQLSPATIAL add-on (using OGR)? Or are there other better approaches to use or settings (inc. PHP) to tweak?
