Nginx + PHP-FPM在Mountain Lion上非常慢

我已经在我的MacBook上使用PHP-FPM设置了Nginx。它工作很好，但是当我在浏览器中运行页面时需要5到10秒才能连接。甚至下面的PHP脚本:

<?php
die();

连接大约需要5秒。我正在使用Chrome浏览器，我在状态栏中得到"发送请求"消息大约7秒。如果我再次刷新，它似乎会立即工作，但如果我离开它大约10秒，它会再次"休眠"。这就好像nginx或PHP要休眠，然后需要很长时间才能再次醒来。

编辑:这也会影响服务器上的静态文件，所以这似乎是DNS或nginx的问题。

谁能帮我弄清楚是什么原因造成的?
