Python 3.1.3 open mbox file, really slow compared to python 2.x?
问题 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
