Cpython

The reference implementation of the Python programming language

Ironpython

IronPython is an open-source implementation of the Python programming language which is tightly integrated with the .NET Framework



Slower files implementations

Example

"After a lot of investigating here are the reasons why i stick to cpython;performance there are some articles out there stating that there are always cases where ironpython is slower so if performance is an issue"

from question  

Pros and cons of IronPython and IronPython Studio

"If there s any heavy application logic as opposed to all of the work being networking files database ironpython is much faster than cpython at a few things and much slower at a few others so you probably need to profile and perf-test before you go too far down either path"

from question  

Python vs IronPython for BitCoin Development

"Ironpython is faster than c# in certain areas but not faster than cpython however you can link ironpython to any language thus over coming problems but then again you can do the same with cpython"

from question  

IronPython vs. Python .NET

"It seems ironpython is just slower than cpython for reading text files"

from question  

File reading and parsing peformance for IronPython vs CPython

"Also on implementations like jython or ironpython could be a lot slower than with cpython"

from question  

Python string comparison pointing to the result

Conclusion faster

Example

"I m not sure exactly how you re drawing the conclusion that ironpython is faster than cpython"

from question  

Why is IronPython faster than the Official Python Interpreter

"Consequently ironpython is potentially faster than cpython is especially for multithreading scenarios"

from question  

Is IronScheme interpreted or compiled? Does it benefit from .NET Framework optimizations?

Jit-compiled jits kind

Example

"Unladen swallow s possible that jython and ironpython are much faster than cpython as well as jython and ironpython are backed by heavily optimized virtual machines jvm and .net clr"

from question  

Why are Python Programs often slower than the Equivalent Program Written in C or C++?

"Ironpython and jython are also jit-compiled although using the more generic jvm and .net jits so they tend to be faster than cpython for this kind of work as well"

from question  

Is MATLAB faster than Python (little simple experiment)

Others

Example

However i know numpy is not compatible with ironpython since it s written in cpython

from question  

How can I use NumPy in IronPython for Revit API?

Cpython probably has better ide support at present than ironpython - so this may be a factor in the choosing of one over the other

from question  

IronPython vs. Python .NET

One of the largest benefits of ironpython is that the largest benefits of ironpython has effectively no gil - meaning that if you are both writing python code and it is multi-threaded - you can often get performance that is better than cpython without having to spawn multiple process and pickle objects across the boundaries

from question  

Iron Python : what are good uses for Iron Python

So if you want to use django or something like that it s probably not smart to use ironpython because it isn t really cross-platform doesn t work with some frameworks and it performs worse than cpython

from question  

Future and stability of IronPython

Rdinary cpython requires python .net to do the same or similar things;in my experience python .net works most of the time but not always and ironpython provides a much more polished experience in accessing .net from python

from question  

Iron Python : what are good uses for Iron Python

I am however no cpython guru and can get so much more out of ironpython than cpython as i can easily leverage the .net platform on which i am far more at home

from question  

How are you using IronPython?

My understanding was it was written in vanilla python cpython but if you are more comfortable with ironpython it shouldn t be hard to translate

from question  

Possible to intercept and rewrite email on outlook client side using ironpython?

I wanted to verify that cpython was in fact waiting to verify the error handler until a decoding error was encountered and that ironpython was not so i checked the source code for both implementations;cpython below is the code for the pyunicode_decodeutf8stateful function found in the unicodeobject.c file for python 2.6.2

String.decode custom errors argument
