CakePHP网站的主页时间到第一个字节是很长 [英] CakePHP site's main page's Time to First Byte is very long
问题描述
我使用pingdom检查网站的加载时间。我发现了来自其他域的一些瓶颈，并修复它们。但最慢的部分仍然存在。
首页在12秒内打开！一秒钟来自所有内部和外部js，css和jpeg文件。 11秒来自主页。我的主页从pingdom结果的详细信息：
DNS 157 ms
连接213 ms
发送0 ms
等待10.5 s
接收56 ms
我把tic-toc beforeFilter和afterFilter的主页控制器。我在一个小时内跑了很多次。结果是主页在0.15和0.35秒之间加载。
我ping了我的服务器，并得到结果为70毫秒。
我还能做些什么来诊断这种延迟吗？
谢谢
strong>修改：您可以查看此链接
编辑2 ：看起来我的应用程序运行0.35秒。 （它甚至没有在主页中的数据库查询）但我可以在10-11秒内在我的浏览器上看到结果。是因为访客负载吗？是否有太多访问者正在使用该网站？
Edit3 ：我仍然遇到此问题。我发现 error_log 的服务器有太多的记录，如下所示。我希望这会提供一些信息：

由于安装了litespeed，在你的服务器上，你会得到超时（慢响应），因为你有错误的配置。查看您提供的日志。我没有litespeed的经验，但你可以试试看这些。

此外，我建议您尝试临时禁用litespeed，以确保它的主要原因。
I used pingdom to check for website's loading times. I found some bottlenecks that comes from other domains and fixed them. But slowest part still exist.
Homepage opens nearly in 12 seconds! One second comes from all internal and external js, css and jpeg files. And 11 seconds comes from main page. Details for my home page from the pingdom result:
DNS 157 ms
Connect 213 ms
Send 0 ms
Wait 10.5 s
Receive 56 ms
I put tic-toc to beforeFilter and afterFilter of main page's controller. I run it many times in one hour. Result is main page is loaded between 0.15 and 0.35 seconds.
I pinged my server and get the result as 70 ms.
What can I do more to diagnose this latency?
Thank you
Edit: you can check results from this link
Edit2: It seems like my application is run for 0.35 seconds. (It even doesn't have database query in home page) But I can see result on my browser within 10-11 seconds. Is it because of visitor load? Whether too many visitors are using the site at that moment?
Edit3: I still got this problem. I found out that error_log of server has too much records like the below. I hope this would give some information:

You have problems with slow page speed because of litespeed installed on your server, you get timeouts (slow response) because you have wrong configuration. Look at your logs you provided. I don't have experience with litespeed but you can try look at these.

CakePHP and suphp socket, connection reset by peer
Also i recommend you try temporary disable litespeed to make sure it's the main reason.
