In spite of widely available high-speed-Internet connections, it is to the blogger’s advantage to insure a fast-loading blog. A slow-loading blog can cause a surfer to mouse-click away immediately. Caching blog pages so they do not have to be PHP generated each time they are viewed can help to keep visitors on your site.
WP Super Cache can help browsers load WordPress blog pages more quickly by caching static versions of the pages in a special cache folder. The first time a page is served, WP Super Cache makes a static copy so that the next time the page is requested, it will be delivered much more quickly.
I found the installation of WP Super Cache to be a bit more complex than most plugins I use. However, when I first tried to activate the plugin, instructions were displayed telling me the steps I needed to take in order to complete the activation. I followed the instructions until the activation process was successful.
If you make styling or template changes after activating WP Super Cache, you may not see your changes. This is so because the old pages will continue to be served until the cache is cleared. An easy way to clear the cache is to turn Super Cache off from within the WP Super Cache Manager and then turn it back on. The Manager is accessed from “Settings” in the admin area. After clearing the cache in this way, you should be able to see your changes.
