Don't know about your tests, but when I looked at this, almost all
crypto timing tests were influenced heavily by cache effects, meaning
that actual mileage is usually much lower than the tests indicate,
especially on a system with a hefty job mix.  Just a caveat --- real
world is larger than it appears in the mirror.
