Well I am pumping out some pretty huge datasets via geoserver, but the
drawing is done WMS. When you talk about performance degradation with
3000 pts, it sounds like you are using WFS which is definitely too slow.
You want to draw with WMS (where you have server-level hardware doing
the drawing using fast code not javascript and where tile caching can
further improve performance), and WFS for querying. If you look at the
SLDSelect example in openlayers, you can even use WMS for drawing the
selection but geoserver doesnt honour SRS in the SLD (mapserver does) so
you have to deal with that in the client.
