Loading 100,000 to 400,000 point data on Map

[PriyaRam]

Hi , I would like to load approximately 100,000 - 400,000 points on the map(from shape file or csv) and the Flex application freezes and is facing a beach ball of death. Has anyone been able to implement this use case successfully. Please advise.

Thanks..

I was once in that dilemma, but no avail finding solution here and there.
To cut a long story short, I did following to improve the performance.

1. What I called it was "screen rule". On each map extent change I cleared the map and added only those points to map that are currently within the screen extent. That reduced points a lot.
The fact is those points that are not visible currently on map are also a heavy burden on map. That made application happy. To further siphon out points I used as described below.

2. In my case I was allowed by my client to add a max and min scale on which a point is visible (I only added point to map on that particular condition). That technique reduced number of points on map and application started to breath.

graphic.visible=false; is not solution at all.

Hope that helped.
Thanks
