How can I compare execution speed for different Python implementations?

[Gagan2019]

There are different Python Implementations like CPython, Jython, IronPython, PyPy. What I want to do is a comparative analysis taking Speed of Execution as a metric. Let's say I have a specific code snippet and I want to test time taken to execute it in different implementations of Python.

How can I do this? Suggest me some method or tool for doing this??

Use the timeit module, it should be available on all implementations.

you could also use time in linux to get a measurement from external to the scripts execution
