Because the encrypted file is *larger* than the clear file with ssh,
which means that you're transfer time will be longer no matter the
size of your pipe.

And, because you're putting the server on the other end under a lot
of stress for no good reason. Which sometimes doesn't matter and
sometimes *really* pisses people off. (Around here, if Oracle can't
have all of the processor most of the time, clients get pissy.)

Or don't encrypt at all if it's not necessary.

And wastes more time. What makes you think the error-correction
provided by TCP is insufficient?
