This is caused by the new mp code. The methods contains(JoinedWay, JoinedWay) and createContainsMatrix(..) are not optimal for large and lots of polygons (both apply to Norway).
And what about the realy large boundary MPs used in Germany and Netherlands (other areas use type=boundary for boundaries).
Maybe we should internaly convert them to type=boundary so that they don't stress the MP code ?

Actually, type=boundary relations can define multipolygons too if they contain enclaves or exclaves. An example would be the city of Espoo, which surrounds the city of Kauniainen: http://www.openstreetmap.org/browse/relation/36097 I am not sure if that would matter, though. Someone might want to define polygons for boundaries (e.g., for highlighting the area), but usually border lines should be enough. Marko
