Python 3.1.3 打开 mbox 文件，与 python 2.x 相比真的慢吗？

我尝试在 python 3.1.3 中使用邮箱模块打开 mbox 文件。里面只有3封邮件，只有27k大。

但是，在阅读邮件时，我的 CPU 使用 100% 大约 2-3 分钟，直到它完成任务且没有错误。

我用 python 2.7.1 尝试了同样的操作，只需要大约 1-2 秒？！

我是否发现了错误或者我做错了什么？我还在 Windows 和 Linux 上对此进行了测试，结果相同:(。

这是我使用的代码，来自文档：

import mailbox
for message in mailbox.mbox('~/mbox'):
    subject = message['subject']       # Could possibly be None.
    if subject and 'python' in subject.lower():
        print(subject)

原文

I tried in python 3.1.3 to open an mbox file, with the mailbox module. There are only 3 mails in it and it is only 27k big.

But when reading the mails my CPU uses 100% for about 2-3 minutes, until it completes it task without an error.

I tried the same with python 2.7.1 and it takes only about 1-2 seconds?!

Did I found ah bug or I'm doing something wrong?
I also tested this on windows and linux, same results :(.

Here's the code I used, from the docs:

import mailbox
for message in mailbox.mbox('~/mbox'):
    subject = message['subject']       # Could possibly be None.
    if subject and 'python' in subject.lower():
        print(subject)
