Indexing for the CDN seems markedly slower on some architectures than others

[h-vetinari]

I noticed in recent days that the indexer for osx-64 is markedly slower than for all the other arches. Most packages are available through the CDN in 15-20min, but osx often takes much longer, like 1-2h.

Not a huge issue, but noticeable during a migration (e.g. Python 3.12, Boost running at the moment).

As my most recent example (I use https://anaconda.org/conda-forge/<package>/files as a proxy; once the download number jumps from 0 to 1, it only takes a couple more minutes for the package to be available, e.g. as verified by mamba repoquery search <package> -c conda-forge -p <arch>):

The other architectures in this example were all available in under 15-20 minutes.

PS: @jakirkham asked me to open an issue here after asking about this on element.

@jezdez do you know who we should talk to about this?
