Just another professional-quality highly effective piece of code from these guys. Insanely simple to load and activate with ONE setting required: "Enabled/Disabled".
Yet, if you want to totally geek-out on the tweaks, they are all there with a MASSIVE amount of explanation. I learn more about WP internals just reading the comments of code written by these guys than the codex.
When I went to my live site to see it work, frankly I was floored. That page loaded so fast I thought I was in a localhost sandbox. And if you're ever in doubt about the cache status, there's a "Clear Cache" button on the admin toolbar that just clears everything.
I am going back to all my websites and replace other cache plugins with this one.
