So...this is an interesting topic. As the name implies, rpm-ostree glues together two fundamentally different "engines" - ostree and libdnf. Theoretically, those config options would apply when downloading layered packages with libdnf. Except today, libdnf doesn't parse the global dnf.conf file, which is (kind of) a bug. Now if you're talking about what the ostree equivalents of those are: they don't exist today. For `fastestmirror` my opinion is that's a lot of complexity that's better handled by CDNs. Which we have configured today for the FAH/Silverblue content, but it's somewhat neutered by https://github.com/ostreedev/ostree/issues/1541 As far as `max_parallel_downloads` - libostree today already uses a lot higher number than the default dnf value of `3`. Big picture the biggest efficiency win for things like this using HTTP/2 which I hope we can re-enable for Fedora soon. Now of course with https://github.com/projectatomic/rpm-ostree/issues/1081 things get a lot easier to understand/manage, as content is fetched in a single way. But the libdnf-vs-dnf.conf issue would still apply. And today librepo doesn't enable HTTP/2 unfortunately, but that shouldn't be too hard to fix.
