I was thinking of ways of speeding up what I (as a user) see as "the slow bits" of Yum. One thing is that Yum has to know when repositories have changed, and currently it uses http or ftp for that. Could it use DNS, as the ClamAV project does? DNS is very scalable, has lots of caching, and is fairly solid. And it's faster than downloading an XML file, because downloading requires a DNS lookup first. % nslookup -q=txt repositoryversion.fedora.redhat.com Non-authoritative answer: repositoryversion.fedora.redhat.com text = "As of 2006-03-28, this repository is at Version 5.0.1. This message's signature: e84f1115fe94" See 'nslookup -q=txt current.cvd.clamav.net' for a working (though cryptic) example. Is there merit in copying this idea for Yum?
