Greetings all, Infrastructure is in the process of getting all of our machines switched from RHEL5 to RHEL6. Right now we're looking at one of the more publically visible services that we host -- mediawiki for fedoraproject.org/wiki. Mediawiki installs and runs for us but it is too slow. So slow, in fact, that our proxy server decides that the instance is down and takes it out of rotation.
If someone has some mediawiki configuration or mediawiki/php programming experience and would like to take a look, we'd be happy to get you permissions to poke around our RHEL6 app server test instance and try out fixes. You can contact nirik (Kevin Fenzi) or me (abadger1999) on irc.freenode.net #fedora-admin to help get you started. You can also take a look at the ticket for any details I've left out here:

Slow for page views, changes or both?

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.

As an update:
The problem was/is that app01.stg runs memcached in staging, but it's firewall was not allowing access to it. :(
Fixing that causes it to load MUCH faster.
We need to reflect that change in puppet now, but it's being tricky.
