上面的朋友测试的似乎他是在本地读取的信息我是从远程服务器上读的。<br /><br />[root@lin1 ~]# curl -o /dev/null -s -w %{time_connect}:%{time_starttransfer}:%{time_total}&nbsp; &nbsp; <a href="http://www.400hosting.com" target="_blank">http://www.400hosting.com</a><br />3.393:3.398:3.728[root@lin1 ~]# <br />[root@lin1 ~]# curl -o /dev/null -s -w %{time_connect}:%{time_starttransfer}:%{time_total}&nbsp; &nbsp; <a href="http://www.400hosting.com" target="_blank">http://www.400hosting.com</a><br />0.028:0.032:0.362[root@lin1 ~]# <br /><br />在西安测试<br />这个是CDN的效果，第二个和第一个明显就少了很多或者本地cookies的作用。<br /><br />有没有人听过8秒定律啊，就是站点如果超出8秒的话，别人就已经等的很不耐烦了。
