I was wondering if using SSL generates a lot more traffic than an unencrypted connection. I can imagine that the key exchange and key renewal can create a little bit of extra traffic, but the use of the symmetric algorithms should generate as much traffic as an unencrypted connection. It takes more computational power to encrypt and unencrypt them using symmetric algorithms, but the size of the exchanged data should remain the same.

Depends on how large your unsecured traffic is. If you have an HTTP(S) connection with small requests and responses (and disconnection after that), then SSL, due to its handshake, can add much more than the size of your request and response is (5-6Kb of data per SSL/TLS handshake is easily possible). But if your requests are hundreds of KBytes (or even multimegabyte) large, then SSL part can be ignored.
