linux – 从某些ISP请求需要很长时间

Linux 前端之家
前端之家收集整理的这篇文章主要介绍了linux – 从某些ISP请求需要很长时间，前端之家小编觉得挺不错的，现在分享给大家，也给大家做个参考。
我们有一台Apache服务器,在虚拟机上运行 PHP.文档根位于用户的主文件夹(/ home / users / {first letter} / {username} /)中,/ home / users /通过NFS挂载.

似乎有些奇怪的事情发生了.当一些用户请求一个文件时(在这个例子中我使用了Hondenbol.png),它需要很长时间(起初用户认为它根本没有加载),而对于其他用户(对我来说,在这种情况下),它几乎立即加载.

这是该vHost的Apache日志文件的一部分.我注意到的唯一奇怪的事情是HTTP状态代码之后的数字,据我所知,这是(来自Apache文档);

2326 (%b)
    The last part indicates the size of the object returned to the client,not including the response headers. If no content was returned to the client,this value will be "-". To log "0" for no content,use %B instead.

同一个文件应该有这么大的差异吗？或者这与浏览器缓存有什么关系？

root@web:/var/log/apache2/vhost# cat VHOST_USERNAME_USERNAME.sinners.be.log | grep -i bol

谢谢,@ kasperd.我将％D添加到日志文件中,并找到了同一个问题的同事.我让他(完全)加载有问题的网站几次.

澄清;页面本身加载正常.只是页面上的图像对某些人来说很麻烦,但它们总是相同的图像.

如您所见,我访问的加载/处理时间要低得多.
所有遇到此问题的人似乎都将Telenet作为他们的互联网服务提供商.拥有Belgacom(这是此处唯一的其他选择)的人似乎没有这个问题.不过,这可能是巧合.这只是我注意到的事情;我不确定这是否相关.

第一个字段集(块)是这里最相关的字段集.

更新3

我们尝试使用非Apache Web服务器(GitLab的Unicorn)并遇到了同样的问题.似乎问题与网络/防火墙问题有关,而不是我们的Apache配置问题.

我们的防火墙和/或踏脚石是使用iptables运行Debian稳定的服务器.

解决方法

状态代码304表示缓存的副本仍然是最新的,并且没有数据发送到客户端.您将看到,对于状态代码为304的所有请求,以及状态代码为200的所有请求的文件大小,字节数都很小.

但是,如果你有一个不错的连接速度,那么传输200KB的静态数据应该只需要几分之一秒.所以这可能不是你想要的瓶颈.

为了调试Apache性能问题,我发现在LogFormat中包含％D很有用.这将告诉您处理请求需要多少微秒.
