Higher zooms (12+) typically take about 1 second per 8x8 metatile per 
CPU thread. 15+ tiles are not pre-rendered for the world, they are 
rendered on demand and cached. The OSMF pre-renders z0-z12 tiles, and it 
takes about a day to do this.

Depending on your hardware, these times could easily change by a factor 
of 2x.
