Hi, Knut Just few ideas.
First thing to try - Sampler i.e. not to use all points, but every 2nd or 3rd -it should decrease ammount of needed processing Another thing- aggregator . Not sure what happens when using aggregator on large ammount of data. But then You could use bufferer. And possibly AreaSmoother.
