Thread:Project:Support desk/Extremely Slow PPFrame DOM::expand

My Mediawiki pages are loading Extremely slow. a 2 minute+ page load time is not uncommon for any page that uses templates. simple page loads relatively quickly. I have gone through every performance enhancing technique for mediawiki to optimize it.

I setup debugging and turned on profiling. The biggest and most common slow culprit appears to be PPFrame_DOM::expand.

Here is an example Performance Output:  Any insight would be appreciated
