Um... It's not like it's a single query. It will be thousands of
individual queries each of which will, on their own, complete virtually
instantaneously.
On top of all that there is time parsing the XML, time running other
ruby code to validate things, etc, etc.
Basically, even if sending a streaming response from rails was possible
(which I'm not sure it is - it's certainly hard) there is no simple way
to measure progress.
