the problem are not only the metadata, but the .solv stuff which did
not exist before DNF was introduced - what the hell is that, why is
it that large and how sould fragment the distribution fix that issue?
Did you think that the faster dependency resolution came for free in
DNF? Yum used SQLite databases, DNF uses solv data. solv data is
generated by libsolv, which parses the repository data and caches it in
a form that can be rapidly re-read and used for doing repository queries
and dependency resolution.
DNF is by far not as fast as pretended and as the additional overhead
and frankly most of the time it's slower, just refuses to just work with
"dnf update *.rpm", gives no useful messages in case of dependency
problems and the whole autocompletion is laughable slow compared to YUM
not talking about missing features like non-ported yum-utils or
essential plugins linke "dnf update --security"
until today nobody was able to show me something which is *really*
faster where it does matter and given that /var/cache/dnf is nearly as
large as the whole OS of some fedora production machines i miss the
improvements and see only drawbacks
