I'd be interested in receiving feedback on my new app that I've built using the Flash Google Maps API:
http://www.TalentMap.jobs/ Currently this app focuses on the Philadelphia region. I'd suggest you run a search on 19103 to guarantee results (center city Philadelphia). The clustering algorithm and performance is what I worked on the most. It's been optimized to a decent level but could be better (as always). I think I can optimize per "zoom level bands" e.g. zoom level 9-11 could query one set of data and then 12-14 would query a separate optimized set of data. A search basically starts by querying the database and narrowing down the data to that within the distance of the provided ZIP code. This will still typically result in a significant amount of data to be displayed on the map. the (typically narrows from millions of rows to perhaps hundreds of thousands of rows). So I have pre-calculated that data further by ZIP code and return that to Flash. This is still a significant amount of data. So an efficient clustering algorithm groups the current Viewport + 50% to allow efficient display of the data. Try it out. I'm able to zoom and pan the data quite efficiently but I'd be interested in knowing whether others experience the same. Thanks!
