网站用于Firefox慢得令人难以置信，即时在其他浏览器：的KeepAlive问题？ [英] Site incredibly slow for firefox, instant on every other browser: KeepAlive issue?

问题描述

我有一个网站，一个网页需要10秒与Firefox加载，并且还有10秒加载图像。这是在Apache上运行PHP页面。这些图像只是静态图像。

它优美运行在镀铬....即时加载。

使用Google的答案指出我朝着与养活一个可能的问题和缺少内容长度混乱的Firefox，而事实上，它看起来内容长度不被设置在服务器上无论是静态还是非静态内容，但禁止在服务器上保留活着一倍加载时间！

一些网站建议禁用保持活动的浏览器，但我不愿意推荐给大家，查看该页面！难道我也许找错了树？

浏览器是清醒山猫的Firefox 3.6.8。服务器是Apache的2.2.11。

的apache.conf是apended ......我认为这是出来的箱的一个，虽然我妄图以尝试并获得页面加载端的超时时间减少到3。

我是找错了树？

解决方案

这个问题是与当地的DNS查找。该问题是由一个事实，即命令行DNS解析似乎是确定，铬是快如闪电隐藏。原来，铬使用DNS prefetching，不使用本地网络堆栈。这把我完全上了错误的策略。

创建本地绑定服务后，火狐似乎很好地工作。

因此​​，一些观看了相同的平台其他浏览器上运行Chrome时。

I have a site where a page takes 10 seconds to load with firefox, and a further 10 seconds to load the images. It's a php page running on apache. The Images are just static images.

It runs beautifully on chrome.... instant loading.

googling for the answer has pointed me towards a possible issue with keep alive and the lack of content length confusing firefox, and indeed, it appears that content length isn't being set by the server on either the static or non static content, but disabling keep alive on the server doubles the load time!

Some sites have suggested disabling keep alive on the browser, but I'm reluctant to recommend that to everyone that views the page! Am I perhaps barking up the wrong tree?

browser is firefox 3.6.8 on Lucid Lynx. server is Apache 2.2.11.

apache.conf is apended... I think it's the one that comes out of the box, although I reduced the KeepAlive timeout to 3 in a vain attempt to try and get the page to load.

Am I barking up the wrong tree?

解决方案

The issue was with local DNS lookup. The issue was hidden by the fact that command line DNS resolution seemed to be OK, and chrome was lightning fast. Turns out that chrome uses DNS prefetching, which doesn't use the local network stack. This threw me onto completely the wrong tack.

After creating a local bind service, firefox seems to be working nicely.

So something to watch out for when running chrome on the same platform as other browsers.
