WordPress

WordPress is blog software that runs on PHP. We recommend use of the WP-Super-Cache plugin for WordPress sites under high load.

WP-Super-Cache

We also recommed you do NOT use the "Latest Comments" plugin for WordPress, as it is known to be poorly written and consume a pointlessly large amount of CPU time and mysql queries.

More information on caching and fighting spam in WordPress can be found in the WordPress_Troubleshooting article.

Question from Oyvind: Is this true only for the "Latest comments" plugin? Does it apply to "Brian's latest comments"? http://code.google.com/p/brianslatestcomments/
