First it depends on the schema of your database. If node table is already clustered by node id, and the way table is clustered by way id, it's going to be at least an order of magnitude faster. Once you've got the tables clustered by id, it's basically a matter of how fast can you write to disk. You're most likely going to be i/o bound. _______________________________________________ dev mailing list [email protected] http://lists.openstreetmap.org/listinfo/dev
