Why Python is faster than Go and C#?

[hsluoyz]

Python is a dynamic language. Go is a static language. There is no way that Go is slower than Python.

And C# is similar to Java in the runtime. So C# should at least faster than Python too.

It seems that Go does not have the best implementation, you can find some issues related in the golang repo.
.Net Core has no compiled regex the performance is worse than in .Net.

By the way, you can run all the benchmarks in your system. In the next days, when I have time, I will add benchmark for Dart and I will run all the benchmarks again in a new machine.

From README:

I hope this benchmark can be helpful for choosing a language but it's not only about performance, each language has its engine and offers different features (like UTF support, backreferences, capturing groups...)
