I recently tested a map application with a total amount of 1000 polylines, consisting of 2 vertexes each. The loading time is about 4s using a 3,6GHZ Intel and Firefox. This is acceptable, however I am aware of the fact that not all people use such a system. I dont want to know whats the loading time with an Eee PC :P
I think I will try to use tile laer overlays, as you said. Thanks!
