[OSM-dev] How is Mapnik Performances ?

[Roberto Navoni]

Hi,
I have a question for OSM-Developer ;)
So I'm trying mapnik for render italian OSM planet , but the performance 
on my sandbox is not so god . I'm using an old one hp laptop that use 
Ubuntu 8.04 as SO and as hardware use P4 3 Ghz 1 GByte of ram . I see 
that actualy are rendering only two  tile for second.  I'm usining 
postgress 8.3 as db. Are there some optimization for speed up the render 
time.
How many mapnik i can start on a single cpu ? The performance is better ?

Best Regards
