Details

With a fresh Arch installation, I was seeing behavior similar to  FS#73977  (but with our tier0 mirror). I was getting the same error but also frequent hangs during -Sy. After much poking around I noticed that core.db was 5 minutes newer than my other machine which worked fine. The issue was gone after an -Syy. :)

Steps to Reproduce:

Run 'make' inside the directory contained in the attached tarball. It should produce a significant delay the second time it does -Sy. It might complete successfully after several seconds of 100% usage of one CPU core.

The above test can be repeated after adding the tier0 mirror from [1] to the top of the included mirrorlist and/or trying other mirrors in the same manner.

With the tier0 mirror I can easily trigger "error: failed retrieving file 'core.db' from repos.archlinux.org : Operation too slow. Less than 1 bytes/sec transferred the last 10 seconds".

Kind of reproduced the same behavior using example curl code, so I reported it as an issue upstream: https://github.com/curl/curl/issues/8626
