I'm not sure how much that mattered. xz -3, which I believe uses a 1 megabyte window, still compresses to 63M. > Could you run your test on a whole planet, Not today. I'm due to receive my new hard drives today, which I bought last friday, so my filesystem is in complete disarray. I'm not even sure which drive/partition I have my whole planet file on, at the moment. I'm sure whatever partition it is, it isn't currently mounted. > or a hack-integration of LZMA into osmosis? That I can definitively say I'm not going to do. I'd sooner reverse engineer the pbf format in C than mess around with the code of osmosis. It took me long enough just to figure out how to install the right jre to get osmosis to run. _______________________________________________ dev mailing list dev@openstreetmap.org http://lists.openstreetmap.org/listinfo/dev
