For a while I've been working in the background to get a sponsored CDN subscription. I am happy to report that Fastly.com has agreed to sponsor the openSUSE project with bandwidth. We primarily intend to use it to improve the reachability (latency) of download.opensuse.org in various areas of the world, but of course can expand it to other usecases as well.
Hm. Although it gives a 4 hop reduction and (with that) a 25% improvement in latency numbers for German Vodafone home networks, that seems also descriptive of the lackluster peering performanace of VF. I digress..
Now, if only libzypp would do parallel downloads, the extra latency of d.o.o would be much less of a non-issue since one would be offered at least a handful of files most of the time... ;^)
I don't know if we can reduce the issues with libzypp just to that. It would be kind of nice to take some notes from other software in the space and allow zypp to query a single file with a list of mirror urls to avoid redirections altogether. That is a feature that existed in dnf for ever, and the only reason why it never worked on openSUSE distros (with dnf) was simply that this was never enabled in mirrorbrain. It also sounds a bit easier to only deal with one request per command instead of one per package on our side, and the local machine is going to be able to tell which mirror has better performance for it (be it latency or bandwidth) than we ever could tell from the redirector.
