Hi there, I'have set up a tiles server based on mapnik that I plan to use (for now) for France only. ( Very good wiki page explaining that) My setup is : debian etch 64/mapnik 0.5.1/postGIS/generate_tiles.py with a quite common machine : dual core 2.5GHZ / 2Go RAM
After much fighting I finaly made it work, and I am happy on all aspects, but speed. While the Mapnik at openstreetmap.org does the rendering (until level 18 if I see it well) in something like around ~24 hours, I am currently doing it for france (600Mo of osm data) until level 14 at a poor ~15 hours time Unless the server over there is a martian one clocked at 10^16 Hz, I think I'm doing something wrong, but what ? I was searching on the wiki/doc at mapnik but didn't find tips for that The only thing I changed in generate_tiles.py is : minZoom = 5 maxZoom = 16 bbox = (-4, 42.0,8,50.0) render_tiles(bbox, mapfile, tile_dir, minZoom, maxZoom) Symptoms to help : - The CPU is fed up at 100% ( load 1.00) - The memory is almost unused (5Mo for postgres !! 60Mo for generate_tiles.py) - The disk is unused - A tile takes ~0.5s to be generated - Severall thousand of "Empty Tile" messages appears during the process, while still taking ~0.5s Does this benchmark looks okay ?
