Howdy, Why pollute the response with data about its performance? I think that data is better placed in a log file (and then you filter approach will work fine). For example, http://www.javaworld.com/javaworld/jw-06-2001/jw-0622-filters.html.
But if you really want to put it in the response itself, I'm not sure why you're not seeing your output, unless somewhere down the chain an error occurs or something closes the output stream.
