From MediaWiki.org
Guaka is Kasper Souren, administrator of several Wikipedias (Limburgish, Bambara, Fulfulde, Wolof), and co-founder of several wikis, such as hitchwiki and the CouchSurfing Wiki.
I'm running several wikis on my own servers and I've worked on several MediaWiki extensions.
I started a page about frontend performance here but it was promptly removed without discussion :(
Funny but sad thing is that I happened to read this between I started the page and my unhappy surprise: strategy:May 2011 Update
I keep a copy here: http://cultwiki.org/en/Cultwiki:MediaWiki_frontend_performance
