On a side note: bw-noicons needs double the time for rendering as osm-no-lables - shouldn't they be more-a-less equal in cpu-time? [The following is only about 'full'-styles] Looking at Zoom 12: http://www.openstreetmap.org/?lat=49.4592&lon=10.9644&zoom=12&layers=M Do we really need a weekly update on that zoom? What you can see is: - main streets (secondary and up) and trains - forests and fields - names of villages and cities IMHO those things don't change often enough to let them jam the queue. Rendering them once a month would be ok. Secondly: Is it correct, that tiles never get deleted? So every tile gets rerendered according to the timetable, no matter if it was requested from a user during that period or not? So maybe a deletion strategy would be handy..
