Mapnik Performace Issue when used with Python

Hi Friends,

I am using mapnik with Python 2.5.
These python script I have to call from my C#.NET application.
As python is interpreted language there will be performance hit when I will render map for whole world.

Do anybody have any solution for following queries:
1. Is there any language instead of Python with higher performance drift?
2. Can I use .NET directly with mapnik class library?
3. Where will I get Optimizing Guidelines for PostgreSQL queries for retrieving Planet.osm data converted into PGSQL.

Any reply appreciated!!!

Thank You !!!

Mapnik's python bindings just call C++ classes, so there is very  
little performance hit to rendering.

Not sure what you are asking here...

Perhaps, if you know how to call C++ from .NET.
