Awesome. Let's make sure Grant and Jon don't have to buy any beers at SOTM.

Changes should now appear much quicker on the map. Many thanks to Jon Burgess, the Mapnik.org guys and the others for making this happen. Technical: The rendering database was switched to an Intel 320 Series 600GB SSD disk, from 4x 300GB 10K rpm in RAID10. PG8.3 -> PostgreSQL 9 with GIN Index FASTUPDATE disabled. Rendering has also switched to Mapnik2 svn r2875. The full DB reload into PG9 used approximately 1TB of the SSD write capacity of a rating of 60TB. Now that only diffs are being applied the write usage has dropped drastically. We'll watch the write usage. Some metatiles are being moved across to the 'old' RAID10 array to improve overall tile IOPs. Tile server munin graph is here: http://munin.openstreetmap.org/openstreetmap/yevaud.openstreetmap/index.html Recent reports of rendering problems should all be resolved now: http://lists.openstreetmap.org/pipermail/talk/2011-April/057651.html http://lists.openstreetmap.org/pipermail/dev/2011-April/022402.html http://lists.openstreetmap.org/pipermail/dev/2011-May/022495.html Regards Grant Part of OSM sysadmin team. _______________________________________________ talk mailing list [email protected] http://lists.openstreetmap.org/listinfo/talk
