Up to about 150, just display them. Up to about 2000, it's reasonable to use MarkerManager or Clusterer in Javascript on the client side.
Above that you need to consider a server based solution. That could be client side clustering or client side marker management (so that each time the map moves or zooms, the client requests a list of markers from the server, and it returns a list of 150 or less) or have a server process that generates tiles on which the markers are painted and use them as a GTileLayerOverlay. -- Mike Williams http://econym.org.uk/gmap -- You received this message because you are subscribed to the Google Groups "Google Maps API" group.
