Thread:Project:Support desk/Very slow Page Load on small Mediawiki Installation

Hi, I am running a small, closed Mediawiki installation. Page loading takes about 10-15 sec and about 2.5 sec per Request (Page, css, js).

The Versions and Extensions I use are: MediaWiki 1.19.2, PHP 5.3.8 (apache2handler),MySQL 5.0.77-community-nt Replace Text, User Merge and Delete, MsUpload, Add Article to Category, DynamicSidebar, Lockdown, WikiEditor

I went through the Mediawiki tuning documentation and tried several caching alternatives like memcache, filecache, apc, ... with no improvement in loading time.

The Profiling output with and without caching is available here: http://stackoverflow.com/questions/16719023/mediawiki-profiling-output-interpretation

Any suggestions on how to improve the performance of my Installation or what exactly the profiling output tells you would help a lot. Thanks in advance!
