== Background == |
|||
This template was written by [[User:Maiden_taiwan]] after the DPL <code>createdby</code> 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: |
|||
<pre> |
|||
<dpl> |
|||
namespace= |
|||
createdby=someuser |
|||
</dpl> |
|||
</pre> |
|||
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. |
