Earlier quoted context omitted.
You benchmarked three different programs and one was compiled to be slow. Why give times for a debug build when the other two aren't? Showing off performance metrics that are both apples to oranges while also giving times for something not made to run fast is total nonsense. Do you really not think this is a mistake? Most people would see C getting outperformed and realize there is something wrong. I'm shocked anyone…
Touch grass my man, you're putting down a CS student's cool project over what compiler flags they used.
Also if someone wants to put their first CS project on the internet, then label it that way and not as some sort of blog post about them doing something unique.
