As both website users and website owners, we want sites to load quickly without long delay. With Google now looking at site performance as a factor in search rankings, it is even more important that a site performs well relative to competitors. Site performance is impacted by a number of factors; one of the key issues is the amount of time it takes the server to generate pages on the site. An easy way to improve your site's performance is to implement caching, which takes some of the load off the server by making copies of frequently used files and displaying them to site visitors, instead of relying on the server to construct/retrieve the files every single time they are requested.
In this recipe, we look at implementing the powerful WP Super Cache plugin. When properly configured, this plugin can achieve considerable improvements in site performance.
