Pushing XML out to a browser request

In a nutshell, we have a back end home grown RPG ERP system with a J2EE
based dealer extranet on top. Part of the function of the dealer interface
is the management of warranty claims. The browser requests claim
information from the back end and the back end produces an XML document in
return. This works great - except - our web comrades complain that it
takes over a full second to get the XML back. They do direct SQL hits to
the DB and get results in a tenth of the time - so they complain. Do you
know of anyone who has struggled with response time related to creating
XML via RPG and passing it back to a web interface? We don't know where
the bottleneck is. It might be on the browser side, but we can't seem to
isolate it.

If anyone has insight about this, I can provide more details to help you
answer.

Many thanks!
