This plugin lists the latest comments on your blog and I wanted to squeeze every bit of performance out of my server so I guessed that caching the output of the plugin would save several queries for every page generation. Comments are cached for an hour. The cache isn’t invalidated by a new comment so don’t worry if the comments list doesn’t update immediately after a comment is made.
I used the same cache directory that WP Cache 2.0 uses,
wp-content/cache/. You’ll have to create that directory and make sure the webserver can write to it. The simplest way of doing that is by running the command
chmod 777 cache. Download the file below and copy it into your plugins directory. If you’ve never installed the original plugin you’ll need to download it and read the install.txt to find out how to use the plugin.
brianslatestcomments.txt – rename to .php and copy into your plugins directory.
