ubuntu上网为什么比sarge慢

liboyang_bj

同样的配置，ubuntu的上网速度比sarge慢很多，浏览网页显示解析半天域名，下载速度也慢了将近二倍。

我看的有关网络的配置文件，就算把sarge的配置文件拷贝给ubuntu也不见改观。

请问这是为什么？

刚安装了Ubuntu，也在学习中，在非官方论坛上看到了这个，不知道是不是这个原因
The latest version of Mozilla includes support for "IPv6" a new form of addressing things on the internet.

The problem is: Mozilla tries to use IPv6 before it uses IPv4 (IPv4 is the old version). When your Internet connection doesn't support IPv6, Mozilla fails to connect on the first try. In the current version of Mozilla, you can't change this, because of a bug.

临时的解决办法是
modutils is used only by 2.4 kernels. mostlikely you have a 2.6 kernel
and you using module-init-tools that uses /etc/modprobe.d/ as
configuration directory.

You need to edit _also_ /etc/modprobe.d/aliases too and run update-modules.

Check that /etc/modules.conf is update properly.

This is the standard procedure. but that's not enough.

Apparently there is another bug somewhere between the kernel and
module-init-tools that even if you ban ipv6 will still allow some
applications to trigger the load of the module.
Personally i don't remember if this is the normal behavior or not.

ntpdate is the first one in the boot process that shows this behavior,
but there are others.

上面太复杂了，还是简单的重命名或者删掉ipv6 module的好

/lib/modules/2.6.8.1-3-386/kernel/net/ipv6/ipv6.ko

不过在启动的时候会产生错误的提示

具体到http://www.ubuntuforums.org/showthread.php?t=171上看吧
