Maybe two more days, but it's really no problem to slow it down a bit. The maximum run time of the current job is bounded anyway with cassini being repurposed.
Okay then I think you should let it run.
Yes I see that, too, but rendering on the fly and then caching the results is a compromise between disk space and cpu power.
ACK. I'll try to get the necessary tool support.
Maybe packing the prerendered tiles into metatiles will solve it for the moment BUT I don't know how it'll be with zoomlevel 18 or maybe 19, 20 or even higher in some high density cities.
