No, it doesn't.  Distributing symmetric encryption/decryption across
multiple general-purpose CPUs seems complicated to me.

However, if you aren't strictly CPU bound, a second processor could
increase throughput, but not substantially, I'm afraid.

However, there's a trivial approach to get something better: split the
file (or the stream) on the sending site and encrypt it in parallel,
using two processes.  (This assumes that you can change the data
