This is method improves handshake performance when your client
many times to your server in short time (like https client connections
with HTTP/1.0).
In this case handshake exchanges only 6 packets (without RSA encryption in
case where
RSA certificates are used) instead of 9/10/12 (depending of authorization

In general: use AES instead of DES3, its faster.
