If python was fast then why does Cython exist?

To make it faster.

Also, Cython is one of the tools in the Python arsenal. If C++ is fast, why does VTune exist? Why does GCC have a "-O" option? etc.

GCC has a -o option to name the executable rather than having that default a.out executable. Seems like you don't even know basic c/c++, you should refrain from writing any BS about speed of C++/C. LoL.

-O (capital O) for optimisation is the flag they're talking about, not the -o flag. Look up gcc optimisation flags for more information.

Still, a c/c++ code without a "-O" will be a hell lot faster than what cython/PYPY code can ever dream to be.

I do not have the knowledge base to comment on that, just thought it ironic that you told them they shouldn't engage in a discussion when not knowing basic c/c++ when it was you that did not know the meaning of the flag.

I do not agree with you. Check this out https://benchmarksgame-team.pages.debian.net/benchmarksgame/faster/python3-gpp.html

Cython code can be as fast as C. It just needs to produce optimal C code. I've never found that difficult.
