[OpenLayers-Users] Large KML file, alternatives?

[Nicholas Efremov-Kendall]

any xml file with 4000+ features will have plenty of node bloat, which is
causing your sluggish performance. Maybe you could produce a raster version
of your shaded map dynamically, which might improve your browser
performance. Otherwise, I don't know that there's a vector format that will
substantially improve your performance, but you should probably look at some
sort of server side solution to the geoprocessing and just display it in
your OL viewer.
