You're basically describing yum-plugin-fastestmirror. Of course that
doesn't get one any sort of parallelism when downloading packages, but
it answers one of your complaints by rating actual data rates.
fastestmirror does not do "data download measuring", which the above
implies. It measures latency (via. connect), which is often a good
substitute and has the advantage of being fast enough. But it can do
obviously wrong things, like ignore a local mirror that had a temporary
It also uses measured data for upto 10 days, by default.
So personally I'd prefer to just rely on MirrorManager. But saying all
that a lot of people swear by it, and CentOS (who don't use
MirrorManager) require it.
