高效的周一：yum-fastestmirror 插件

Fedora 的镜像服务器遍布世界各地。如果一台 Fedora 系统需要浏览软件包信息，安装软件包或者更新系统，它首先会访问 Fedora 服务器，下载一份镜像列表。这个列表是根据发出请求的系统的体系结构、IP 地址和具体要求的仓库，自动生成的。

yum-fastestmirror 插件为 Yum 提供了衡量现有镜像速度，将其排序，首选最快服务器的功能。这样，yum 操作可以加快，也有助于减少网络拥塞。安装插件之外，不需要任何手动配置！

命令行安装：
yum -y install yum-fastestmirror

图形化安装： 不在浏览列表中，需要搜索 yum-fastestmirror
安装后菜单位置：没有菜单选项，没有为 yum 或者 PackageKit 提供新的子命令，自动通过 /usr/bin/yum 和 /usr/bin/pkcon 生效

原文见 Productive Monday: yum-fastestmirror – Use fastest mirror for downloads

Fedora uses a worldwide system of mirror servers to distribute packages. When a Fedora system needs pacakge info, packages, or updates, it will by default request a mirror list from a Fedora server. This list is generated based on the repository and architecture requested as well as the IP address of the requesting system.

The yum-fastestmirror package provides a Yum plugin which measures the speed of available mirrors and sorts the list so that priority is given to the fastest mirrors; this can result in faster yum operations and reduced network congestion — and with no additional manual effort beyond installing the plugin.

Installing from the command line: yum install yum-fastestmirror
Installing using the graphical installer: Not available by browsing; search for yum-fastestmirror
Menu location after installation: Not on the menu; alters the operation of yum and PackageKit
Command: No direct command; access functionality via /usr/bin/yum and /usr/bin/pkcon
