I am trying to make an img/tdb/overview from massachusetts.osm (downloaded from cloudmade). My computer is a mac with 2G of ram. The .osm file is 2.4G. While running with 1024m heap size java ran out of heap. With 2048, it is moving along, but paging a lot wiht a RSIZE of 1750M and getting only about 2% on cpu, and now up to 4m35s of runtime. Should I expect this to finish? I would like a routable map - the cloudmade ones aren't routable, and I'd like to be able to tweak styles to emphasize hiking trails. I think it would be nice to give some rules of thumb about input sizes somewhere, prehaps in a README in the sources, in terms of what the max sizes that work are, how long they take, and what the needed RAM/RSS is. It would also be cool to have an output file or stdout that counts the resources used somehow.
