Status: Beta

The current Map framework is relatively slow, especially marker and polyline operations are costly, since are translated directly in JavaScript, thus happen online, instead of using one of the provided offline 2D drawing libraries like Quartz, CoreAnimation etc.
The route-me project offers solutions to this and also provides implementations for CloudMade, Microsoft VirtualEarth and OpenStreetMap(OSM).
