>What sort of spec machine are we taking about for a GB extract? The main problem is less the osm2pgsql extraction (which can be run in slim mode to conserve memory) and more the speed of accessing the postgis database to grab the data. My current machine (Bytemark VM) has 1GB memory, 20GB disc space, 1 core. See: http://www.bytemark.co.uk/hosting/virtual_machines With caching the generated GeoJSON data and a cron job to re-render tiles, this can (only just!) cope with an extract covering part of England and all of Wales, see http://www.free-map.org.uk/0.6/about.html#village Not sure, without looking up, what percentage of the data is used by Freemap, but given London, Birmingham etc are missed out, as well as the whole of Scotland and most of the Midlands and East Anglia, I'm guessing abput 25% or so. I can check later though. Nick
