Google maps API - JavaScript vs Flash - what's faster?

I draw on the map about a thousand of si开发者_如何学Pythonmple polygons using JavaScript API V3

I'm not so happy about performance, especially on IE - it takes about 90 seconds to draw all polygons and the map became hardly responsive

There is any chance Flash API deals with a large amount of polygons better then JavaScript?

Yes. The Maps API for Flash will generally handle a large amount of polygons better than JS.

You can also get some strategies for improving performance from this talk, given at Google I/O 2009:
