Hi,

Tile CDN is highly loaded during daytime and not loaded on night.
There is a peak after each stylesheet update. Monitoring:
https://munin.openstreetmap.org/openstreetmap/render.openstreetmap/index.html#renderd


I propose to enlarge rendering queue. This will let to use night CPU time
to render tiles that will likely be requested again tomorrow. Real time
usage should not be affected, as tiles are going to top of the queue on
request.

Pull request is here:
https://github.com/openstreetmap/mod_tile/pull/152
please review, comment and help to make it happen :)
