Page views definitely.  Changes probably.  onekopaka looked into this
yesterday and we made a change to the mediawiki caching configuration that
seemed to help but something is still wrong.

We're seeing 10+ second page loads for app02.stg (RHEL6) compared to less
than 1 second for app01.stg (RHEL5).

I've just taken app01.stg out of rotation so if you browse to a page on
http://stg.fedoraproject.org/wiki/

That no one else has seen yet (so it isn't yet cached), you should see the
10+ second delay.
