well Struts applications can be optimised HTML for the specific task. While Web Dynpro has some standard HTML which comes with a certain overhead. Also the CSS is larger than needed foroptimised applications (also the CSS is only loaded once).
Its difficult to say how much overhead, depends on the complexity of your HTML.
