2017 golang, python, php, C + +, c, java, nodejs Performance Comparison [cont.]

Recently busy, This topic put a few days, today to a sequel. Previous portal: 2017-year golang, python, php, C + +, c, java, Nodejs performance comparison (golang python PHP C + + java Nodejs performance)

well, Some of the last things some people have objections, today also responded.

1. Some people say that Python performance is not that low?

This I used PyPy 2.7 confirmed, It is not so bad, if you use NumPy or other version of python, the performance is Faster. But PyPy is not perfect, pypy3 in beta, so the general situation, I mean in general, this is more Unpleasant.

2. Some people say that there is no such thing as C #, Rust, ruby?

I just want to speak the language millions, too many, but the energy does not put on the tool, chooses a suitable is good.

Really want to see, also have:

Let's See.

　　

finally, add a big picture to show everything

But the figure does not count compile time, the dynamic language is not fair.

In addition, performance difference is not small, who developed high efficiency, who is the king, obviously go is the future star (perhaps to add one, haha), Nodejs potential!!!
