The counterpart of pyramids for raster are generalizations for vector  
data, reducing the number of vertices for a geometry.

Look here

http://docs.geoserver.org/stable/en/user/data/featurepregen.html

and

http://docs.geoserver.org/stable/en/user/tutorials/feature-pregeneralized/feature-pregeneralized_tutorial.html

The standard configuration is an XML document, but I personally use a  
plugin fetching config data from the database.

In case of further questions, please ask.

Cheers
Christian
