I advise to eventually cross check those numbers against C++ 
modules.

In Visual C++, the C++23 "import std" (which includes the 
complete standard library), is faster than a plain "#include 
<iostream>".

Naturally for the forseable future, C++ modules are something 
that only Visual C++ users can enjoy, as other commercial vendors 
with forks taken out of GCC and clang aren't that keen into 
providing upstream support for better ISO C++ compliance.
