Example? I'm curious

Python is generally around 50 times slower than C++. Obviously it varies massively with the benchmark but that's a good ballpark.

Just Google "python vs c++ speed" and you will find hundreds of examples (or "python vs rust speed" - Rust is essentially the same speed as C++).

Here's the first result - they got a 25x speedup:

Did you read the article and comments? The comments point out a lot of issues with the article. Sadly, I've seen this article referenced before on other discussions.
