There is a rather annoying side-effect of mirrorlists -- mirrors may not always be in sync, so quite often I issue "yum list updates" and see that there are updates, but when I run "yum update" it hits a different mirror, where these updates are not yet available. As a side-effect, it has to download and parse primary.xml.gz for updates each time the mirrors are not in sync, which depending on the connection and processor can take a significant amount of time. I get around it by forcing -C (cache-only mode) after initially running yum to get the repomd.xml, but others may not know about it. I don't have any solutions to propose, unfortunately, other than mirroring an admittedly confusing behavior of apt, which requires specifically issuing "apt update" to get new repository medatada. However, especially in the cases where domain resolution takes forever (some ISPs, in a vain attempt to combat spamming from zombie clients, throttle down DNS responses to take 10-15 seconds), non-cache operations with mirrorlists take quite some time more than -C.
