This is completely hopeless methodology, of course you will
not get useful results this way, the time for a Free is
orders of magnitude faster than the clock resolution.

I recommend looking at the PIWG tests or at the ACES tests
for examples of how to do timing in a meaningful way.

In fact unless you have a lot of experience in the construction
of meaningful benchmarks, I think you will find the ACES
quicklook to be a much more meaningful comparison that tests
that you prepare yourself. There are simply too many pitfalls
in benchmark construction :-)
