You are talking about using the Geotools renderer and rendering many layer.  I 
am talking about Other renderers such as the MapGraphic Renderer that is trying 
to do simple animation.  When a MapGraphic re-renderes it is the only renderer 
that is triggered and there for can very quickly request that the result be 
displayed.  I was only able to get frame rates of 1-1.2 frames per second.  I 
would like to see at least 2 frames per second if not much better.  Also since 
the conversion process takes such a long time I know that it is causing lower 
end clients to have problems.
