Indeed, and a lot of the code is likely to be running 'cold cache'.
I was alluding to the problem where people will benchmark a small function
by running in 1000s of times in a tight loop with exactly the same data.
Not only is it 'hot cache' but any dynamic branch prediction is 'trained'
to the specific data.
