I am running MediaWiki on dreamhost for two websites. The first gets about 50,000 page views a day, the second gets 12,000. Dreamhost is using mediawiki version 1.16.4 and shows no interest in upgrading to version 1.17, let alone 1.18. I recently moved from Apache to nginx as a web server, but it doesn't seem to have helped very much. I'm running PHP 5.2.x FastCGI (default) which is the only thing dreamhost supports with nginx.
- How do I make MediaWiki run with less ram and faster? Will upgrading to 1.17 or 1.18 make a difference?
- How do I tell if caching is enabled? I have the PHP configuration managed by Dreamhost and PHP cache enabled. (It claims to use XCache.)
- Is there anything else I should do?
