On some of our sites, we almost nowhere are able to rely on the caching system because of have dynamic elements on each page that cannot be captured by relying on the request based caching of magnolia. One approach that could truly speedup our rendering would be to allow dedicated caching of areas that are to be rendered, as most of the areas are static and only some of them have dynamic content. I think it would be not so hard to implement if you gave me a hint how I could create a custom areaTag that uses a custom AreaElement for rendering. I would be willing to provide my implementation as a prototype implementation.
