Example

• {{Slow}} gives:

Warning: This keyword can result in very slow and inefficient queries on your MediaWiki system, potentially impacting performance for all users (see bug report).

Background

This template was written by wikia:User:Maiden_taiwan after the DPL createdby keyword hurt performance on his MediaWiki system significantly. On a MediaWiki site with 100,000 articles and 3,000 users, this DPL took 2.5 minutes to run:

<dpl>
namespace=
createdby=someuser
</dpl>

People were making these DPL calls all the time to find out what articles they had created. When two of these ran at once, it significantly hurt wiki performance.
