Yes, that is why we have staging and production servers.

I would not treat the patches as the final UI or final logic that we
will use for 3.4.  It is just a way to test the SF mirror under some
load.  We can revert these patches once the test is over, or move to
something else.

For example, we might have logic that sends 75% of the traffic to SF
mirrors and 25% to Apache mirrors.  We could adjust that with a
parameter in the script and tune it based on capacity.
