Page rendering should now be much faster (~15%). Memory usage has also decreased dramatically (~70Mb vs. 120Mb after a clean start).
In the next month or so, we'll be rolling out MediaWiki 1.19 (which brings the benefits of 1.18; we are currently on 1.17.4).
A reminder for those going to Califur: the UMA awards ceremony is at 4PM on Saturday. I expect a strong turnout of WikiFur supporters!
