Comment(by karsten):

 weasel just said on #tor-dev that 1 AES operation may not be correct for
 16 written or read bytes.  That number doesn't include TLS on incoming and
 outgoing side.  So, a middle node would do AES-for-TLS, AES, AES-for-TLS,
 that is, 3 AES operations.  An exit wouldn't do the final AES-for-TLS, so
 just 2 AES operations.  But 3 may be a good upper bound here.

 Does that make sense?  Or is 3 AES operations per 16 bytes of relayed data
 still totally off?
