For those using the yum-fastestmirror plugin, the fastest mirror is determined by the time it takes to resolve the mirror name and to connect to the server's TCP port. In particular, it does not measure the bandwidth from the mirror. This method isn't perfect, but it does usually pick one of the nearest mirrors. Sometimes there are some oddities, as you have noticed. Try sort -k 2 /var/cache/yum/x86_64/6/timedhosts.txt or sort -k 2 /var/cache/yum/timedhosts.txt , those commands will list the connection times to the mirrors yum knows about, sorted by measured connection time. http://miuku.net/tmp/testconnectiontime.py.txt can be used for running connection time benchmarks on your own. That script has been extracted from yum-fastestmirror. _______________________________________________ CentOS-mirror mailing list CentOS-mirror at centos.org http://lists.centos.org/mailman/listinfo/centos-mirror
