php - CakePHP 站点主页的 Time to First Byte 很长

Question

我使用 pingdom 来检查网站的加载时间。我发现了一些来自其他领域的瓶颈并修复了它们。但最慢的部分仍然存在。
主页几乎在 12 秒内打开!一秒来自所有内部和外部的 js、css 和 jpeg 文件。 11 秒来自主页。 pingdom 结果中我主页的详细信息:

DNS 157 ms
Connect 213 ms
Send 0 ms
Wait 10.5 s
Receive 56 ms

我将 tic-toc 放入主页 Controller 的 beforeFilter 和 afterFilter 中。我在一小时内运行了很多次。结果是主页在 0.15 到 0.35 秒之间加载。

我 ping 我的服务器并得到结果为 70 毫秒。

我还能做些什么来诊断这种延迟？
谢谢

编辑:您可以查看 this link 的结果
Edit2:我的应用程序似乎运行了 0.35 秒。 (它的主页甚至没有数据库查询)但我可以在 10-11 秒内在浏览器上看到结果。是因为访客量大吗？此时是否有太多访问者使用该网站？
Edit3:我仍然遇到这个问题。我发现服务器的 error_log 有太多记录，如下所示。我希望这能提供一些信息:

由于服务器上安装了 litespeed，您会遇到页面速度缓慢的问题，并且由于配置错误而导致超时(响应缓慢)。查看您提供的日志。我没有 litespeed 的经验，但你可以尝试看看这些。

CakePHP and suphp socket, connection reset by peer

此外，我建议您尝试暂时禁用 litespeed，以确保这是主要原因。
