It is the cross-platform and open-source replacement of the .NET Core project and the .NET project that ran exclusively on Windows since the late 90’s. See the conference about it if you want to go deeper. Performance: I just saw a SO post about someone complaining their Python was 31x slower than C#. The most common way around this performance barrier is to compile Python extensions from C or using something like Cython. .NET 5 CLR comes bundled with a performant JIT compiler (codenamed RyuJIT) that will compile .NETs IL into native machine instructions on Intel x86, x86-64, and ARM CPU architectures. Pyjion is a project to replace the core execution loop of CPython by transpiling CPython bytecode to ECMA CIL and then using
