I'm trying to draw using open layers a collection of polygons and multipolygons that I retrieve using JSON that represent the US county boundaries. I've used a smoothing algorithm to reduce the number of points by about 80% when using IE. It displays in under a minute using Firefox. It takes about 6 minutes to display in IE.
I've created a refresh strategy and set the update interval to 0. So I shouldn't update the layer unless I've just added the polygons. Which I draw using redraw. I have everything in the same projection. I've used a javascript and haven't discovered anything unusual. Does anyone else have any other suggestions? Doug
