I think your posts on this topic can not possibly be worth responding to if you're coming to the conversation with this level of not understanding things.

Your post is a combination of not understanding computers and then hand waving about fake numbers and user expectations. IO is not magic, it is not some distinct process that you have no control over from userland, it is exactly the sort of thing that Python does very poorly at, in fact.

I'll just reference techempower again, or you can look up those system calls you referenced like how epoll works and then look into what is involved for Python to use epoll effectively.
