[arch-general] Rollback to specific date works fine -- but really slow download
Arch folks, Had the need to do a first rollback to 3/15/22 for a samba bug report on 4.16 failure to discover [homes] (https://bugzilla.samba.org/show_bug.cgi?id=15062). The rollback worked flawlessly, but is there anything that can be done to help the download rate? Due to the ICU 7.0->7.1 update, there were 368 packages in 1.3GiB to download. At 300->500KiB it took forever. -- David C. Rankin, J.D.,P.E.

Have you tried using the mirrors (https://{europe,asia,america}.archive.pkgbuild.com)? They all seem to have varying speeds.

Yes, (I think so) I followed the wiki and modified mirrorlist to contain: Server=https://archive.archlinux.org/repos/2022/03/15/$repo/os/$arch Originally, I just wanted to downgrade samba, but due to the ICU 7.0 -> 7.1 update a huge number of dependencies were broken, and that's where the roll-back really saved the day. I didn't use the "Historical Archive", from reading the wiki, that wouldn't have been doable in this case. -- David C. Rankin, J.D.,P.E.

No, in this case it was just archive.archlinux.org. I'm crossing my fingers that, other than this samba bug, I shouldn't need to do it again. I just wanted to confirm that the 300-500KiB I was getting in download was normal or if I had missed something on the wiki page. Even if slow, the archive is invaluable for circumstances just like this, and I can understand why limiting the download may help create a balance for the use of the archive. So if there wasn't anything I missed, and 300-500KiB is about what you would expect from archive.archlinux.org, then all is well. Thank you for the mirror note. If I ever have to use this again, I'll try a mirror and see if the rate improves. Otherwise, I was able to get the level 10 debugs and tcpdump traces for the samba bug after the rollback completed. -- David C. Rankin, J.D.,P.E.

I am getting ~10MB/s right now, though also observing some missing packets and latency jumping on one of hoster’s routers to multi-second range despite normally being 30ms from them.
So under 512KB/s reported by you is not too fast. But I would not be concerned about that for the reason I mentioned earlier: it’s not a mirror meant for daily use.
