I am working with Geoserver, serving U.S. Lower 48 counties to openlayers (3109 polygons - lots more vertices). The counties are loaded into a postgis database. I am curious about developer experience when trying to push that quantity of vertices to the client.
What WFS format have you attained the best results with? Has additional tuning to Geoserver been used?
I realize that tiled WMS would be faster, but I want to allow for dynamic changes in a choropleth map using openLayers, ie. the user submits a form, a Python script is called, and new data bins are returned for openlayers to reload the map div. I also want to try this in full resolution form before reducing polygon complexity in openlayers.
