CloudFlare - Free Reverse Proxy, Firewall, and Global CDN

CloudFlare is a FREE reverse proxy, firewall, and global content
delivery network and can be implemented without installing any server
software or hardware.
On average, CloudFlare-powered websites load 30% faster, use 60% less
bandwidth, and process 65% fewer requests. CloudFlare-powered websites
are protected from many forms of malicious activity including: comment
spam, email harvesting, SQL injection, cross-site scripting, and
DDoS(denial of service) attacks.
That sounds fine and dandy, but can I see the performance of
CloudFlare-enabled site?
