[OpenLayers-Users] Performance Tuning in Internet Explorer

[jim.meyer at concept-solutions.com]

Hi Christopher,

	We are using GeoServer (not MapServer).  Is there a way to take all
of the client-side options and pass them in a request to GeoServer so that
GeoServer will interpret and style the variable shape data correctly?

Thanks,
Jim

There isn't naything that you can do in OpenLayers that you can't do with
some other server side rendering code -- either using MapServer or some
other
tool. You really aren't going to be able to render that many things at once
in a clientside browser.

Other suggestions people have offered, like setting a max for features
returned at 100 or some such, also likely bear investigation.
