As for having multiple datastores implement it, you're right it's a matter of volounteer time, but what can we do about this? It's not as bad as having a custom renderer for a specific data format imho, in that it separates out the two tiny things needed to get a performance boost. > The code for very efficient decimation and reprojection is available in > the Shapefile renderer so it must be rescued from there. Yeah, for non database data sources it would be good. For jdbc data source, efficient decimation means make the server do it, not our code :) > I will book an afternoon to do decimation and reprojection for shapefile > but it will have to be a quick implementation so I may need some help > testing and bug fixing.

Jesse, I'm wondering, is implementing this hints good enough to say bye bye to the shapefile renderer and have back a single renderer? (oh joy, that would be so good).
