Chrome 31 deployed a new TLS cipher suite based on Prof. Dan Bernstein's ChaCha20 and Poly1305 algorithms. They run three times faster than AES-GCM on devices that don't have AES hardware acceleration, including most Android phones. These have now made their way through the standardization process. We'll be deploying the standardized variant in Chrome 49.
