Something very useful Fedora or RHEL users in terms is to configure YUM, download from quickest network speed package repository. On RHEL and Fedora developers made it be a piece of cake.
All you have to do is run command:
[root@centos]# yum install yum-fastestmirror
That's it the package installs one python script which, takes care of finding the closest RPM repository for your distro as well as check among a list of RPM mirrors which one is fastest and has lesser hosts ( hops ) to your system. It is pretty much like Debian's netselect (the tool on Debian which finds nearast fastest deb repository), except it is much simplistic. Once yum-fastestmirror package is installed you don't need to do nothing else, the script is loaded as a YUM plugin so it does all work on finding closest repository by itself. The list of all mirrors, among yum-fastestmirror will evaluate is:
[root@centos ]# grep -i host /etc/yum/pluginconf.d/fastestmirror.conf
hostfilepath=/var/cache/yum/timedhosts.txt
maxhostfileage=10
[root@centos ]# wc -l /var/cache/yum/timedhosts.txt 50 /var/cache/yum/timedhosts.txt
The whole list of RPM package mirrors as of time of writing as taken from CentOS 5.6 is here
