在使用PHP时，请不要提及性能.如果您想开始问这些问题，也许您应该研究网络编程.作为喜欢玩网络编程的人，我应该警告您，这不是一个琐碎的话题.

Please don't mention performance when you're using PHP. If you want to start asking those questions, perhaps you should be looking into network programming. As someone who likes playing with network programming, I should warn you that it's not a trivial topic.
