How is the selection done? How is the highlighting done? Those processes will really impact performance depending on how things are implemented.

The data displays nice and quick when just viewing, but if I allow the user to select say 5000 cells 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 - would just transferring the shapefile to to say a MS SQL 2005 db with the MSSQLSPATIAL add-on be a good step or is there are better way to present the data in the Map file?
