This is just a hunch so I might be wrong. Worth checking out though: Normally you shouldn't use indexes when doing a large import. Just create them after the import has finished. This is due to the constant need to rebalance the Tree (which I presume they use for the index). But as I said: I have never used MongoDB so far and this is just a general observication. _______________________________________________ dev mailing list [email protected] http://lists.openstreetmap.org/listinfo/dev
