Is zypper slow for you?

Where's the slowness at, would be a more accurate question. * The download of metadata and rpms still appears to be serialized, which means network _latency in establishing TCP connections_ (of which there are a few, or even a lot) is really visible. * Building the repository caches could be faster (especially on machines a few generations old). * I guess some people can argue that funneling a number of requests through download.opensuse.org (even if that itself does redirects) is not the best way; latency accumulates in this step too.

Mirrorbrain works on the simple premise that a national connection will be faster than an international or an intercontinental. That is just not always true. For instance, for many Canadian users, connections to the US are frequently better than domestic connections, e.g. to Canadian university mirrors. I second the question of "where is the slowness?" - is it e.g. about pure download speed? The European mirror infrastructure is well populated, as is the North American - Africa and South America are a lot less supported. Asia (including the far East and the Middle East) looks like it do with some improvement. -- Per Jessen, Zürich (10.4°C) Member, openSUSE Heroes

Maybe you can vote NO (not slow non-EU) for me. Reddit requires a login I refuse to create. -- Evolution as taught in public schools is, like religion, based on faith, not based on science. Team OS/2 ** Reg. Linux User #211409 ** a11y rocks! Felix Miata

Already made my comment and applied your suggestion of using mirrocache-us and things are better at least for zypper, my main drive-to-insanity is with osc.. which talks to download.opensuse.org and it is there when things always go wrong..and it starts downloading from some Brazilian university of who knows where.. of course I can't blame the system for doing something that makes sense which is to choose the nearest mirror.. unfortunately here faster mirror means "as near as possible to the nap of americas" not "as near as possible geographically".

The poll seems to imply that this is a bandwith problem, but from my experience it is not necessary. For a default one repo setup it's not slow, but if I add more and more additional repositories, espeically ones which moves in the same speed as Factory, it's getting slower and slower... And for the dnf fans: I don't see a real difference there.

More repos certainly make things worse, and repos that churn frequently amplify this because you necessarily have fewer up to date mirrors. Zypper nor DNF do not fix anything there. For *me*, I switch to using metalinks so that I can get something and DNF can failover to other mirrors easily rather than just straight up failing. -- 真実はいつも一つ！/ Always, there's only one truth!
