检查不同服务器之间加载时间较慢的原因 [英] Check the cause of slow loading time among different server

问题描述

一家电子商店已经开发出使用perstashop并投放到三台服务器：前两个是亚马逊，应该是相同的设置

服务器1：
http：// be -pure.com/en/women/3-slim-y-tank.html

服务器2：
http://52.77.216.83/en/women/3-slim-y-tank.html

最后一个只是本地托管服务器

服务器3：
http://internal001.zizsoft.com/be_pure/en/women/3-slim-y-tank.html

问题是服务器1的加载速度与其他两台服务器相比非常慢，但性能应该是3之中最好的。

它看起来好像服务器1没有缓存文件

但实际上它们都有

打开smarty缓存，使用文件系统，修改$ b时重新编译$ b和
打开文件系统缓存

鉴于代码和服务器设置是相同的，两个amazon服务器都是相同的设置，而本地主机一个是其他服务器，但它应该比服务器1慢1）如何调试/检查文件是否已使用缓存？

（缓存文件位于服务器的cache / smarty和cache / cachefs中）

2）服务器1需要很长的加载时间？只要把它当作一个PHP站点，任何方法来检查它为什么很慢？

非常感谢帮助

解决方案

请参阅评论 - 我误解了我之前看过的数据。看来服务器一次只能处理5-10个请求，所以事情会被阻塞，直到其他事情完成加载。您可能只需更新您的Web服务器的配置以处理更多请求。

文件中还有很多JS数据。加载页面只有318KB，并且在获得任何HTML之前，它必须做很多JS / CSS文件的请求。所以它是318KB +所有需要获取的外部JS / CSS（哇！）。这就像4MB的东西只是为了加载一个页面。

检查由缓存系统生成的文件的修改时间戳，以验证缓存是否正常。

编辑：

由于现在有奖励 - 请回顾我们的评论讨论。有一个问题，traceroute没有到达服务器的目的地，我怀疑这是与缓慢有关，但是这种类型的网络问题已经过去了。

A e-shop has developed using perstashop and put to the three server:

the first 2 is amazon, should be same setting

Server 1: http://be-pure.com/en/women/3-slim-y-tank.html

Server 2: http://52.77.216.83/en/women/3-slim-y-tank.html

the last one is just local hosting

Server 3: http://internal001.zizsoft.com/be_pure/en/women/3-slim-y-tank.html

The problem is server 1 loading very slow compare to the other two server, but the performance should be the best among 3.

It looks as if server 1 hasn't cache the files

but in fact, all of them has

turn on smarty cache, using file system , with recomplie when modify and turn on the file system cache

Given that the code and server setting are the same, both 2 amazon server is same setting, and localhost one is other server, however it should be slower than server 1

1) How to debug/ check whether the file is using cache already?

(the cache file locate in cache/smarty and cache/cachefs in server)

2) And what takes the long load time for server 1? Just consider it as an PHP site, any ways to check why it is slow?

Thanks a lot for helping

解决方案

Refer to the comments - I misinterpreted the data I was looking at earlier. It appears the server can only handle maybe 5-10 requests at a time so things get blocked until the other things are done loading. You likely just need to update your web server's configuration to handle more requests.

There is also a lot of JS data in the file. It is 318KB just to load the page and it has to do many requests to get JS/CSS files before it even gets to any of the HTML. So it is 318KB + all the external JS/CSS it needs to fetch (wow!). That's like 4MB of stuff just to load a page.

Check the modify timestamp on the files generated by your caching system to verify that caching is working.

Edit:

Since there is now a bounty out - please review the comment discussion we had. There is an issue where a traceroute doesn't make it to the server destination and I suspect that is related to the slowness but that type of network issue is over my head.
