Setting Up WP Super Cache

By default, WP Super Cache is caching off, so you have to enable it in the configuration page. To do this, go to Setting -> WP Super Cache, and click on the Easy tab. Turn the cache on and click on the Update Status button. Don’t forget to test whether this plugin is working or not with the Test Cache button.

Note that WP Super Cache fetches 2 pages of your site at one time. If the timestamps on both pages match, then it means this tool is totally functional.

Advanced Settings

In addition to this basic setting, there are also many advanced options that you can choose to further improve the performance of your site. According to our experience, we highly suggest the following configurations.

Check the boxes next to “Cache hits to this website for quick access” and “Use mod_rewrite to serve cache files” as they are the recommended options by the developers of this plugin. In terms of Miscellaneous part, you can configure it based on your real situation and needs, but we still suggest you staying the same as the following image.

After switching for mod_rewrite, you have to update your .htaccess file at once. To do this, simply scroll down on the Advanced page, find the Update Mod_Rewrite Rules button with a yellow background, and click it.

In terms of Garbage Collection, the default setting is 3600 seconds, which is suitable for a site featuring 1,000 or less posts with a low update frequency. If your website contains more than 25,000 articles, a lower setting of 1800 may be better to prevent any stat/CPU issues. Therefore, simply go to the Expiry Time & Garbage Collection section under Advance settings page, enter 1800 in the box next to Cache Timeout, and then hit the Change Expiration button.

Lastly, don’t forget to set the CDN option, which serves the static files well, such as JavaScripts, images, and CSS, etc. If you are confused about this service, check this post for more information.

To set up it with WP Super Cache, select CDN tab and check the box aside with “Enable CDN Support”. Then, enter your local URL with a format like http://cdn.yourdomain.com. After checking the box which is next to “Skip https URLs to avoid mixed content errors”, click on the Save Change button immediately.
