Does anyone actually use the FastestMirror knob in DNF? Can I have your Opinions and Thoughts on the feature? #Fedora #Linux

@kwf I wish it didn't exist. People turn it on thinking it's a magic 'go faster' button, but it just sends you to the mirror with the lowest latency, which is very often not the mirror that has the fastest actual downloads. ;(
@nirik @kwf what it needs is a test file on each mirror. Find the ten closest (for example) using ping and then do a download test to see which is actually faster.
@justin @nirik mirror operators would hate it. They're already struggling with IOPS and bandwidth and you want to turn them into speedtest servers that aren't doing any useful work?
@kwf @nirik what other way would there be to get the fastest server?
