\subsubsection{Superscalar out-of-order speculative execution}
You must be aware that modern processors \emph{do not} execute machine code in a linear way, as laid out in the source code. This can lead to counterintuivive timing results reported by Tracy. Trying to get more 'reliable' readings\footnote{And by saying 'reliable' you do in reality mean: behaving in a way you expect it to.} would require a change in the behavior of the code and this is not a thing a profiler should do. Instead, Tracy shows you what the hardware is \emph{really} doing.
This is a complex subject and the details vary from one CPU to another. You can read a brief rundown of the topic at the following address: \url{https://travisdowns.github.io/blog/2019/06/11/speed-limits.html}.
