Is Golang actually as fast as C/C++?

Answer 1

Isken I don't think so. This is my source
https://benchmarksgame-team.pages.debian.net/benchmarksgame/fastest/go-gpp.html
Also click on the languages mentioned on the top of the page to see comparison with other languages.

While Golang was slower than C++ and Rust, it was as fast as C# and Java and much much faster than Python. The main reason is that Golang uses something called garbage collection for memory management which has some performance penalties, while C++ and Rust don't use it.

Answer 2

We'll try and see
Try to make an app in c++
Then make an app in go
Then test and see the startup

Answer 3

I think Golang is "the fastest" programming language in multithreading. Those benchmarks are made on one thread.
