Here is a small hint for developers:
The displayed result does not need to be shockingly up-to-date. The information listed on the main page (http://www.wikidot.com) is also cached for some period of time.
It should be more important to create an efficient way of fetching and displaying data and handling dozens of req/s than displaying up-to-date content. This is why we encourage using Memcached.
