I have installed MediaWiki 1.15.1 and am finding that it is intermittently very (very) slow - often working fine, but othertimes taking up to three minutes to load a simple page.
Googling finds that MediaWiki should be installed with a PHP accelerator.
My ISP has pointed me to its status page so I can see what versions of 'stuff' they are running - it is at http://www.netregistry.com.au/support/kb/questions.php?questionid=59
which shows that they are running Zend Accelerator.
I'm guessing I need to modify my LocalSettings.php to tell it to use Zend - any clues what I might add/change?
Any other tips greatly appreciated
