Hi OSM,<br><br>The OSM tile server has been upgraded over the last few days. Changes<br>should now appear much quicker on the map.<br><br>Many thanks to Jon Burgess, the <a target="_blank" href="http://Mapnik.org">Mapnik.org</a> guys and the others for<br>making this happen.<br><br>Technical:<br>The rendering database was switched to an Intel 320 Series 600GB SSD<br>disk, from 4x 300GB 10K rpm in RAID10. PG8.3 -> PostgreSQL 9 with GIN<br>Index FASTUPDATE disabled. Rendering has also switched to Mapnik2 svn<br>r2875.<br>The full DB reload into PG9 used approximately 1TB of the SSD write<br>capacity of a rating of 60TB. Now that only diffs are being applied<br>the write usage has dropped drastically. We'll watch the write usage.<br>Some metatiles are being moved across to the 'old' RAID10 array to<br>improve overall tile IOPs. Tile server munin graph is here:<br><span><a target="_blank"
