Subject Re: Weblog tagcloud / performance
Date Thu, 12 Nov 2009 17:01:08 GMT
The Weblog Entry tags query is done against a tag-statistics table and
so it should be fast.

All Roller Weblog pages are cached by default.

Have you done some performance testing that shows a problem with tag
performance?
