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


(The older version, WP-Cache, has a nasty bug, you probably shouldn't use it.)

We also recommed you NOT to 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.

Along the same line, OpenID should also not be used. As described in a blog-post, this plugin can be misused and you will be a target of CPU overuse spam. Your server will be instructed to initiate numerous (and continuous) PHP instances to pr0n/3rd-party websites, in order to extract the fake OpenID user's name & email information, which will consume CPU minutes and slow down your website.

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