The above is just a random representative sample. The results are
pretty close when running this test, but I can average up several runs
and present the numbers. I plan to get a bare-metal test box on which
to run some more detailed testing and maybe some profiling this week.

Just contributing more runs into the mean doesn't tell us anything about the
variance. With numbers that close you need the variance to tell whether it's
a significant change.
