This is easily the best wordpress plugin hands down. The developer has spent years of his life he will never get back to provide this FREE plugin. The level of detail that this plugin goes to in order to increase performance of your site means that everyone will not have the same expierence. Do your homework, search the internet for guides, thoughts, and understanding of how this plugin works and what settings are most appropriate for your situation. If your after a easy button solution this is probably not it. Try WP Super Cache instead. If your interested in the absolute best caching plugin with CDN and cloudflare integration,(they make this far too easy) than this is it.
