[Dang Ngoc Chan, Christophe]

Hello,

I have a limited understanding about these topics,
but here are a few things I know or guess:

Some instructions are stored so the execution is faster when it is performed twice.
This is not unusual when the second execution is faster than the first one.

I guess the number of cycle is divided by the frequency to have a time in seconds.
