[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.
