[OpenLayers-Users] Recommendation for large number of points?

[Andreas Hocevar]

18,000 POIs are impossible to handle on the client. Consider using a WMS
(like GeoServer or Mapserver) to render your POIs, and use
OpenLayers.Control.WMSGetFeatureInfo or OpenLayers.Control.GetFeature to
make the POIs interactive.

Regards,
Andreas.
