The proximity check is slowing down rendering considerably. I have 6 clients at work at the moment, 3 of them have already exceeded the 6 hour limit: 946,1652 (since 6:06 MEST) 2097,1374 (since 11:14 MEST, layer tile finished at 20:00 MEST) 1072,1577 (since 13:57 MEST) Until now, my clients were _much_ quicker.
