Power Complexity

W3 seems to be a fairly powerful and flexible caching plugin. This power and flexibility, however, comes with complexity. Be prepared to look through a tutorial or 3 in order to get it set up properly.

Also, it seems to be best to turn off the caching plugin when making changes to the site theme or styling, as it doesn’t always reflect your latest changes.

I use this on all my sites, but I wish it wasn’t quite so difficult to use.
