Increasing WP-Cache performance for blogs with heavy commenting

Dec 29

Caching is the key to success – the more content you cache, the more visitors on the same hardware you can serve. Many WordPress owners run wp-cache plugin to cache blog pages in files, rather than generating content on the fly – querying MySQL database. If you have a low usage that is fine, but if you have a medium load blog or getting Dugg/Slashdot effect – only tuning, optimization and proper caching will keep your blog up and running.

wp-cache will need to regenerate cache file every time a blog post receives a comment – performance is lost if the post receives heavy commenting. You can hack wp-cache plugin to expire cache for particular page only when cache expire time expires, not with every new comment.

Open the WP plugin directory – wp-cache plugin file: wp-cache-phase2.php

and comment out line:

add_action(‘comment_post’, ‘wp_cache_get_postid_from_comment’, 0);

// add_action(‘comment_post’, ‘wp_cache_get_postid_from_comment’, 0);

And you are set.

  1. Hi,
    do you know what is optimum time to set for “Expire time”? Can I set it to 86400 sec – 1 day?

    Thank you!
