Felix,

did you compile the Europe map with generate-sea=multipolygon?
My speed improvements of 75% were generated with this option. I also 
think that this is the best of possible speed improvement with this 
patch ;-)

It is important for me that no major problems are observed with it. I 
think I will have a look on it again within the next week. There should 
be some more improvements in cutting.
