[OpenLayers-Users] Performance Tuning in Internet Explorer

[jim.meyer at concept-solutions.com]

Hi Till,

   We are using a lot of checkboxes on the client-side to generate a complex
query that determines which shapes to display.  This information is sent to
the server where a complex query runs and returns JSON to the client with
the shape data.  These shapes are rendered in a different color based upon
their time to activation.  I don't believe they are static enough to be able
to use WMS.

Thanks,
Jim

Jim,

if it is just necessary to *SHOW* the shapes you probably might check to 
serve them as WMS (try UMN  or GeoServer) or pure as UMN-CGI service ?

Doing that, your performance is an issue of the WMS server and not of 
OpenLayers and there are many screws to work on like indexing, 
scale-dependency and so on...and you are more browser independet, 
because the only thing to show is an png or gif image.
