Thanks for your analysis and your patch. I do not have enough time to check if the patch produces the same valid results. But to me it sounds like a good aproach. Therefore I created a branch memory_optimization including your patch so that your changes might be tested more easily by a bigger group of people. The compiled release of the branch should appear automatically at http://www.mkgmap.org.uk/splitter/. If that's not the case Steve might has to do some configuration stuff on the webserver? WanMil

This patch reduces memory requirement in splitter by ~50% by replacing class SparseInt2ShortMultiMap with class Node2AreaMap. It also includes small performance tweaks.
Still not solved by this patch: - Memory usage depends on the highest node id in the data. - Node id> Integer.MAX_VALUE do not work (not a problem at this moment)
If this small patch is okay for you, I can provide a bigger one that also fixes these issues, but touches many more files
Ciao, Gerd
