And once again I have to issue the reminder: you can have gains or
losses of several percent on microbenchmarks of this kind just by
touching unrelated pieces of code that are never used in the test. In
order to demonstrate a consistent difference, you have to do each set of
tests multiple times, with random amounts of padding added to some
unrelated part of the code.
