Hello Erik, Displaying that quantity of polylines will not have very good performance(pan and zoom) with the standard API.
There are a few different things some of us have tried. Usually the best approach is to make a custom overlay that can draw a group or set of your polylines to limit the number of overlays the map has to manage (reduces events, panning is much simpler etc). I haven't used KML, but I'm going to assume that the performance wouldn't be any better than normal polylines. Take a look at the following posts: http://groups.google.com/group/google-maps-api-for-flash/browse_thread/thread/4c24c498f143593f?hl=en http://groups.google.com/group/google-maps-api-for-flash/browse_thread/thread/52dc36c1a82ba119?hl=en Let me know if you need any additional details. I've done the custom overlay route with good performance with thousands of lines.
