Fabio,

> The new CPUs have or they will have all some formalities that suit him for the request of power of calculation (to reduce the consumptions); when it is required to the CPU to work this increases the performances with various algorithms, all of this it creates a latency (around a 0.5-1.0s) during which the performances are not 100%. The loop forces the CPU to go themselves to regime before making the measure.

Thanks for that tip. I will use the same technique for any benchmarks I do in the future.
