Benchmarks of curve25519

Preliminary benchmarks on the upcoming curve25519 implementation display why it is listed as being a speed record breaker. On average, a TLS connection using curve25519 with RSA signature, 128 bit AES and SHA is approximately 15 percent faster than when using NIST curves with the same suite. When using the recently released ChaCha20-Poly1305 suite and curve25519 the TLS connection time is even faster than that of the AES suite. Curve25519 so far is destroying the key agreement and generation benchmarks of previous curves, putting up numbers for both key agreement and generation that are on average 86 percent faster than those of NIST curves.
