Super Cache is one of the two best caching plugins for your WordPress blog, and will help to speed up load times by compressing and decreasing the size of files. But is Super Cache a built-in plugin of WordPress that is part of the WordPress core?
Nope, Super Cache is an independent plugin that must be installed separately and in addition to the WordPress core files. The plugin is free to download and use on your blog, however, although donations are of course appreciated.
Super Cache is not developed and maintained by the same group of people who work on the WordPress software itself. The plugin is written and maintained by Donncha O Caoimh. He is solely responsible for updating it and making sure that it is compatible with new WordPress updates and other plugins.
This is actually good thing because Super Cache is a large and complex plugin which is best suited to be kept out of the base WordPress files. To ensure stability, WordPress core files are kept to a minimum, and certainly not every blog owner wants or needs a caching plugin for his site.
So after you have installed WordPress on your new blog, you will need to download and install the Super Cache plugin separately. The configuration for the plugin is relatively easy when compared to some of the other caching plugins and shouldn’t take long at all.
