Hi!
I have done some profiling. Rendering a single tile takes an average of
1979ms. Of this time, 1814ms are spent on mapnik rendering, the
remaining 165ms are file I/O and image conversion/blending. So it is the
rendering that needs optimization in some ways.
Are there any tricks for getting it faster? Constructs to avoid in the
osm.xml?
Is it helpful to create indices on the DB? Currently there are none.
Other than that, Metatiling looks promising, I think I'll have to try to
get the script to somehow do multiple tiles in one go.
bye
Nop
