Of these languages, C# may actually be the fastest.

In most cases the later entries in a language for the benchmark game are increasingly hyper-optimized and non-idiomatic for that language, which is exactly where C# will say "Here's some dangerous features, be careful" and the other languages are likely to suggest you use a bare metal language instead.

Presumably the benchmark game doesn't allow "I wrote this code in C" as a Python submission, but it would allow unsafe C# tricks ?

Unsafe C# is still C# though. Also C# has a lot more control over memory than Java for example, so you don't actually need to use unsafe to be fast. Or are you trying to say that C# is only fast when using unsafe?

Likely just that the fastest implementations in the benchmarks game are using those features and so aren't really a good reflection of the language as it is normally used. This is a problem for any language on the list, really; the fastest implementations are probably not going to reflect idiomatic coding practices.

Here are naive un-optimised single-thread programs transliterated line-by-line literal style into different programming languages from the same original.
