Do any package managers use bittorrent? I associate bittorrent with distributing large files, but it seems like it would really help scaling.
Most traffic to package managers is from CI systems, which could instead run their own local seeding nodes.
lib rs has a bunch of interesting statistics about the number of crate authors, the number of dependencies, etc.
For example, weekday traffic is now 2.3x of weekend traffic, so presumably more folks are using Rust in their day job.

It'd be interesting to normalise against total web traffic size.
