Seems like https://developer.mozilla.org/en-US/docs/feeds/<format>/revisions (e.g. https://developer.mozilla.org/en-US/docs/feeds/atom/revisions) isn't been being gzip'ed which would result in far less network traffic. E.g. right now the revision feed for en-US is ~4MB and could be compressed to ~161kb with highest gzip setting.

For the stage environment, I've added application/atom+xml to the list of MIME-types that the load balancer will deliver as compressed.  In testing, it looked like it added a little under a second of processing time on the initial load of the file; the file is then cached, making subsequent access fairly quick.

@jezdez - Can you verify that this works as intended before I apply the same change to production?

@cyliang Yeah that works as expected, the feed on stage only transfers ~70kb and prod ~600kb with similar endresults once unpacked. Let's apply that to prod as well. Thanks!

I applied the change to production and cleared the cached atom feeds from the load balancers (to help force them to be compressed).  Keeping this open a few days to see if there are any unanticipated negative side effects.
