IronPython(适用于.Net的Python)比同一台计算机上的常规Python(cPython)要快.为什么是这样?我认为编译后的C代码总是比等效的CLI字节码更快.

IronPython (Python for .Net) is faster than regular Python (cPython) on the same machine. Why is this? I would think compiled C code would always be faster than the equivalent CLI bytecode.

推荐答案

Python代码无法编译为C，Python本身是用C编写的，并且可以解释Python字节码. CIL被编译为机器代码，这就是为什么在使用IronPython时会看到更好的性能的原因.

Python code doesn't get compiled to C, Python itself is written in C and interprets Python bytecode. CIL gets compiled to machine code, which is why you see better performance when using IronPython.
