Yes it looks like we're underusing the CPU on the box. Last night I changed the number of renderd threads to 8 from 4. I'm not sure what the threads are doing exactly but I thought each one was rendering and that the master process handed out things to render. There's also a distributed renderd patch available, but that's only if you're using multiple machines: http://trac.openstreetmap.org/ticket/2005 _______________________________________________ Maps-l mailing list [email protected] https://lists.wikimedia.org/mailman/listinfo/maps-l
