Pyhton Interpreter启动时间 [英] Pyhton Interpreter Startup time

问题描述

你好，


我正在寻找一个小应用程序，它需要一个非常快的启动时间来为Python解释器启动时间。它没有做太多（复制

和文件缓存，没有GUI）但我需要Python解释器以非常快的速度启动

（<1秒开启一个Windows框）。有没有办法让一个

''剥离''Python解释器，它可以在一个

的Windows框中快速启动。我曾经想过的事情是使用PyExe来快速启动它（它是否编译成C代码，因此在运行时不使用

Python解释器？） 。这是一个可能的解决方案吗？


我观察到我第二次启动python它启动得更快

但是我假设这取决于环境并且不能依赖（或类似的东西）。


先谢谢你的帮助。


干杯，

Neil

你有什么样的机器？


在我看来，Python在大约0.06秒内启动......


这个原始测试在Windows XP机器上显示这些结果

（它不能用于Windows 98，因为它无法在
这样的命令行，但你可以在批处理文件中。）


c：\> echo。 |时间& python -c" import time; print time.time（）"

当前时间是：8：59：59.67

输入新时间：

1092315599.73


这是一台相当快的机器（Athlon 2500+），但我真的好了b / b
怀疑速度慢的机器需要的时间比1秒钟长很多

除非他们真的*老了。

Hello,

I''m looking at a small app which would need a very quick
startup time for the Python interpreter. It doesn''t do much (copying
and caching of files, no GUI) but I need the Python interpreter to start
up very quickly (<1 second on a Windows box). Is there a way to have a
''stripped'' down Python interpreter which can start up very quickly on a
windows box. Once thing I was thinking of was to use PyExe to make a
quick startup (does it compile down to C code, therefore not using the
Python interpreter at runtime?). Is this a possible solution?

I observe that the second time I start python it starts up quicker
but I''m assuming that this is dependent on the environment and can''t be
relied upon (or something like that).

Thanks, in advance for your help.

Cheers,

Neil

What kind of machine do you have?

On mine, Python starts up in about 0.06 seconds...

This primitive test shows these results on a Windows XP machine
(it won''t work with Windows 98 as it can''t chain commands on the
command line like that, but you could but it in a batch file).

c:\>echo. | time & python -c "import time; print time.time()"
The current time is: 8:59:59.67
Enter the new time:
1092315599.73

This is a fairly fast machine (Athlon 2500+) but I really
doubt slower machines would take much longer than 1 second
unless they are *really* old.
