关于Ubuntu网速慢的问题

Ubuntu
Ubuntu 网速慢，主要是把时间浪费在域名解析上。我们可以用dnsmasq解决这问题。
具体如下：
安装dnsmasq
命令: sudo apt-get install dnsmasq
编辑dnsmasq的配置文件
命令: sudo gedit /etc/dnsmasq.conf
找到下面这一项
#resolv-file=
用下面的一条语句替换
resolv-file=/etc/resolv.dnsmasq.conf
确保你没有更改过/etc/resolv.conf文件，如果改过，恢复原状
然后执行命令
sudo cp /etc/resolv.conf /etc/resolv.dnsmasq.conf
然后编辑resolv.conf
命令;sudo gedit /etc/resolv.conf
将其中的域名服务器全部去掉，加入以下这行
nameserver 127.0.0.1
如果用路由上网也可以加上路由的地址
保存，退出
执行以下命令
sudo gedit /etc/ppp/peers/wvdial
在 usepeerdns 前面增加 ＃ ，也就是把这条语句覆盖掉。
以防，resolv.conf的设置被pppoe覆盖。
重启电脑。不重启，你会发现无法解析域名。所以一定要重启电脑，来达到重新启动dnsmasq的目的。
重启后， 你会发现解析速度比以前快了N个数量级。
选择最近的源也可以进一步提高网速
在终端中输入；
$sudo gedit /etc/apt/sources.list 清空后把源地址复制到这里面
$sudo apt-get update 第一个update完之后接着
$sudo apt-get upgrade
