I am rendering the whole world up to zoom 5, and from 6 to 8 central Europe, but 9 to 15 only a part of Italy (43 to 40.6 lat), so the fewer data for NZ would get compensated by the bigger area. I use a really basic setup though, which is not efficient (no metatiles), so I guess there is room for optimization. I am sure in a few days you can render all of NZ with an ordinary desktop. also If you want to keep up to date, apply diffs, and render at the same time you will need something bigger then my setup. cheers, Martin ___ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk
[OSM-talk] rendering map tiles with mapnik - hardware requirements
we at OSM New Zealand are looking at rendering our own (NZ-only) tiles, and we'd like to get a rough idea of the hardware requirements we will need are there any rules of thumb for how long it would take to render a given lat/lon bbox, using mapnik? i assume lat/lon is the independent variable, although i guess density/complexity of data will affect things as well. disk space, cpu, ram, time would be useful cheers, -- robin http://tangleball.org.nz/ - Auckland's Creative Space http://openstreetmap.org.nz/ - Open Street Map New Zealand http://bumblepuppy.org/blog/ ___ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk

These two metatiles rendered in 18 seconds and 1.5 seconds. So it can be all over the place depending. This box is busy doing other things too. http://weait.com:8080/map/shield.html?zoom=6lat=-41.73199lon=173.35156layers=BFF zooming in to CHCH metatiles were well under a second. You can get by with a modest box as long as you don't mind waiting and have little load. OSM has a monster with 96GB ram and many fast disks in RAID. You can probably keep a good size group happy with a quad core 8 GB ram 1 TB of disk And the faster you can make your disks the better, as per Frederik's presentation at SotM last year.

The thaimap.osm-tools.org is running on a virtual machine. It has 1GB of guaranteed RAM and 2x2 GHz guaranteed CPU. neither load nor RAM seams to be a problem. Maybe disk-io could be a problem in a shared environment. Stephan ___ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk
