与其他.net语言相比，ironpython的速度如何？-Howdoesironpythonspeedcomparetoother.netlanguages?

Here are two interesting links with comparisons between IronPython, CPython, and C# (among others):

以下是两个有趣的链接，包括IronPython，CPython和C＃（以及其他）之间的比较：

• CPython vs C# (Mono) benchmarks, based on several programs detailed on the site.
• CPython与C＃（Mono）基准测试，基于网站上详述的几个程序。
• CPython vs IronPython benchmarks, based on PyStone and PyBench, for versions 2.6.
• 对于版本2.6，基于PyStone和PyBench的CPython与IronPython基准测试。

So apparently it does along the lines of what your professor told you. But as you know, it depends so much on what you are using.

显然，它确实与你的教授告诉你的一致。但是如你所知，这在很大程度上取决于你所使用的东西。

The difference is mainly due to the dynamic nature of the objects used in Python, whereas C# is strongly typed. So IronPython uses one more level (the DLR - Dynamic Language Runtime) on top of what C# is run from (the CLR - the Common Language Runtime), to resolve this difference.

差异主要是由于Python中使用的对象的动态特性，而C＃是强类型的。因此，IronPython在运行C＃（CLR - 公共语言运行时）之上再使用一个级别（DLR - 动态语言运行时）来解决这种差异。

I usually hate to cite Wikipedia articles, but this is a good starting point: http://en.wikipedia.org/wiki/Dynamic_Language_Runtime

我通常不愿引用维基百科的文章，但这是一个很好的起点：http：//en.wikipedia.org/wiki/Dynamic_Language_Runtime

Now to come back to your project, the performances will probably be more dependent on your algorithms/heuristics - how you query a database for example - than on the language. If you are familiar with a web framework and are happy with it, it's a good idea to stick with the same environment rather than gain a possible few percents on something you'll have to tame first. It wouldn't be the same if the application was CPU-intensive of course.

现在回到你的项目，性能可能更依赖于你的算法/启发式 - 你如何查询数据库 - 而不是语言。如果您熟悉Web框架并对它感到满意，那么坚持使用相同的环境而不是获得可能首先要驯服的东西的几个百分点是个好主意。如果应用程序当然是CPU密集型的，那就不一样了。

You could enable .net tracing, which outputs timing information at the bottom of the page. Make an app in C#/.Net and an app using Python and look at the differences in timing. That will give you a definitive answer.

您可以启用.net跟踪，它会在页面底部输出时序信息。使用Python在C＃/ .Net和应用程序中创建应用程序并查看时间差异。这将给你一个明确的答案。

In all honesty I think you're better off just using C#, it's "faster" to develop since the VS environment is there for you and it's going to run faster since it doesn't have to use the dynamic language runtime.

老实说，我认为你最好只使用C＃，它的开发速度“更快”，因为VS环境适合你，而且它运行得更快，因为它不必使用动态语言运行时。

IronPython will be considerably slower than C#. You could think of the comparison as very roughly between CPython and C, but with the gap somewhat smaller.

IronPython将比C＃慢得多。您可以将CPython和C之间的比较视为非常粗略，但差距会略小一些。
