Using a caching system on your blog, you will increase the speed of it. When some user browse your webstite for first time, and a cache system is burning, website will be copy on user’s machine, so when the same user back on your site for second time, his navigation is half from local, and half from server.

By this way you will reduce loading time, but also hosting band, database query, and other tecnical skill from your server. If you are a developer, I suggest to turn every caching system OFF because, browsing the same page a lot of time, more probably you can’t see what you have modified.

1. W3 Total Cache:

This one, uses another kind of solution, this plugin, starting from your dinamically (php) version of your blog, edit it in a static (HTML) version. This solution, is only provided to:

  1. Users who are not logged in.
  2. Users who have not left a comment on your blog.
  3. Or users who have not viewed a password protected post.

Plugin also cache website in 3 ways; depending from speed of solution:

  • Mod_rewrite;
  • PHP. Supercached static files can now be served by PHP
  • Legacy caching. This is mainly used to cache pages for known users.
