Hi Chris,

thanks a lot for new splitter beta release. I tried your version with a small region (Bayern in Germany). Max nodes 800.000, 12 tiles:

old splitter: 310 MB RAM
new splitter: 240 MB RAM

old splitter: 370 sec
new splitter: 470 sec

old splitter: problem with 31 relations in more than 4 tiles
new splitter: no problem

old splitter: problem with 2 ways in more than 4 tiles
new splitter: problem with 2 ways in more than 4 tiles

So this is basically good news: memory requirement decreased, and the problem with large relations disappeared. The performance is not as good as the old splitter version, but this is not a problem for me. 
Is it possible to improve your code so that large ways can be in more than 4 tiles?
