The best solution to solve the CentOS network speed is extremely slow

Excerpt from: http://www.centoscn.com/CentosBug/osbug/2014/0614/3138.html

I used CentOS, but found that the speed is almost impossible to access the Internet, even Baidu can not open, but win is fast. Later think of accidentally remember once saw a paragraph, said to close IPv6, test come, really effective, close to IPv6 open speed fast. Close method:

1 vi/etc/modprobe.d/dist.conf2#结尾添加 3     alias net-pf- off   4     Alias IPv6 off  

Then save and restart CentOS.
