Assuming your client-side processing is optimized as possible (i.e.
you're using the browser to parse the XML).

FYI, Wave doesn't rely on the browser's XML support. Given Google is obsessed with performance, that makes me wonder if com.google.gwt.xml.* is the best choice. Admittedly, Wave never supported IE; but my point is: you'd better benchmark. Did you know that some browsers (Chrome IIRC) are actually faster at building things with a "detached DOM" than string concatenations and innerHTML?

 

Are you converting the XML to HTML? If so, perform the conversion on the
server and send the generated HTML to the client. Manipulate the DOM on
the client. GWT excels at that work, as it is designed to reduce
DOM-related memory leaks.

Either that or send JSON; or actually anything but XML (IIRC, Wave only sends the initial document as XML, everything else is actually JSON-based, from protocol buffers definitions)
