CCM is short for "Counter with CBC-MAC". I does also MAC the encrypted data and is equally slow as using a cipher and HMAC on top of it. A real speed improvement would be the Galois Counter Mode.

In my experience, speed isn't an issue. The only slow part of any of this is PBKDF2, unless you're dealing with huge files (not the case in chat).
