It has nowhere near the performance characteristics of those languages. It could, but it doesn’t. Look up a variety of language benchmarks. It’s typically ranked around Python/Javascript. You can get as fast as C but the code is very atypical.

There's no way it's close to Python. Where are the benchmarks?

Shows a huge difference, as expected for a typed memory-safe compiled language using LLVM versus an interpreted language with a global interpreter lock.

The thread you just posted has a bunch of posts indicating this was not the actually the same program in Python and Swift; further, the Swift version was written poorly. Plus, the graph in the final post shows whatever Swift version someone ran tests on as much faster than Python.

It is slower, like probably ~3x but lets not exaggerate that it ranks around python
