Why POE is slower then Python - Twisted ... quite a lot?

I have 2 simple scripts which connect to NNTP server to fetch 100
articles (no writing to local disk) in order to test the performance
of two frameworks.

I have found Twisted is faster by at least 2 times which make me surprised.

I know it is not fair to compare two frameworks by this simple test.
But I think 2 times is quite much.

Therefore, I upload the code online to see if any experts can find any problem?


Thanks.
