WP Super Cache settings

WP Super Cache is a caching plugin for WordPress that helps to speed up your website. This blog post outlines the recommended settings to get optimal performance out of WordPress.

WordPress is a fantastic tool for creating flexible websites that are easy to maintain. Unlike some content management systems, it is relatively lightweight as far as system resources are concerned, therefore it will run smoothly on almost all hosting packages. Despite this, it doesn’t hurt to give it a little helping hand.

By default, when a WordPress page loads, it is making a number of database requests to the server, all of which adds to the loading time. Maybe it’s requesting the page title, the content, a series of images, a list of recent comments, the five most recent blog posts – the list could go on. Each of those elements makes another database request. What WP Super Cache does is save a static copy of that web page to the server, then loads that instead of having to make all of those server requests. The result is that each page should load noticeably faster, making the user experience more pleasant and also keeps search engines happy, since they now take page load time into account when determining search rankings.

So… once WP Super Cache has been installed, follow these points to get the most out of it:

  1. Under the “Easy” tab, make sure “Caching on” is selected and click “Update”.
  2. Under the “Advanced” tab, make sure that the following are selected:
    – “Cache hits to this website for quick access”
    – “Use mod_rewrite to serve cache files”
    – “Don’t cache pages for known users”
    – “Mobile Device Support”
    – “Extra homepage checks”
  3. Then click “Update”.
  4. Scroll down until you see an “Update mod_rewrite rules” button then click it.
  5. Scroll down again until you see “Rejected User Agents” – clear all of these and click “Save UA strings”.
  6. Under the “Contents” tab, click “Delete Cache” then click “Delete Expired”.
  7. Under the “Preload” tab, enter 10080 in the “minutes” field, make sure the “Preload mode” box is ticked, then click “Update Settings, followed by “Preload Cache Now”.

That’s it. To test if this has worked, log out of the WordPress admin, clear your browser cache and reload your website’s homepage. Right-click and view the page source and scroll right to the bottom. You should see “<!– super cache –>” on the very bottom line, with a time stamp above that.
