My personal experience with CloudFlare is that it is best configured as a CDN for your public static front-end. Any CSS, JS, and images will see bandwidth reductions. That being said, for the back-end I've never seen improvements. If CloudFlare detects a server error, it could show a static optimized page which is great for anti-DDoS protection but the recovery on their end was significantly slower (minutes behind). It's an unnecessary layer in the protocol.
