We have very few mirrors in India to begin with. While we generally request mirrors have 100Mbit or faster connections, we will make exceptions for areas where we have few mirrors and where we have had little luck finding volunteers to run faster ones.
Matching users to mirrors based on country isn't perfect, and I'm always open to better algorithms. I recently added a lookup for clients and mirrors connected via Internet2 or one of its peers. If someone can describe how to better guess the network topology, exactly for cases such as yours, I'm all ears.

In India getting bandwidth of at least 25 Mbps is next to impossible . so you need to work with slower ones . Wbut mirror got recently upgraded to 8mbps line . One more point getting speed from depends on ISP provider (client side ) also . Even located just 180 KM from wbut mirror I wont get anything better than 30 KBps . My ISP does permit more than that . While some other guys in different ISP gets much better speeds .

Hi, Matt, Maybe you could finagle an angle with one or more of those speed meter sites? Maybe the mirrors would or could run a speed meter application accessed by the RPM software to assess speed prior to establishing the connection. Something like a quick burst to check 3 or 4 sites then choosing the best one?

sudo yum install yum-fastestmirror
gets you most of this. It works fine with mirrormanager too.

All the more reason to reduce the yum update process, if at all possible. Via 28.8 it took about 4 hours before the mirrors settled down on Friday night to where the yum process could proceed to do useful work. I have not run an entire "update all" process since installing F7. I can't, for all the mirror problems and/or the dnload failures and pure slowness of the sqlite.gz business. Please presto that sucker and if some sort of signal to yum indicating that the mirror isn't available or sync'ed yet, for yum to jump past, that would be pure-eyed SWEET! We'd have the best mechanism for install/updates available on the net. The Debian camp could eat crow. :) Ric

Ha! Like me you have an emotional stake in this, and the fingers get ahead of the brain. I feel ya! Ric
