Using default options: indentation, references to char. entities, etc, saving a 2,274,219 bytes long DocBook 4 document takes less than 600ms on my Linux laptop (having a slow disk drive like most laptops). The problem seems specific to DocBook 5, and more precisely to indentation when the document being saved conforms to a RELAX NG Schema. If you turn indentation off, you should be able to save your document in no time (less than 50ms). This is clearly a problem, but we currently don't see how to improve the performance[*] of XXE in this case and we currently do not plan to save documents in a background thread. --- [*] Of determining the ``type'' of the element being indented, which is different from validation and which is a complex problem to solve in the case of RELAX NG.
