Cargo is downloading excessively slow.

Problem

I am talking about 36 kb/s speeds:

And, okay, I am living in a literal shithole, like we are still using 3G but my internet is still not that bad:

Is this a bug of some sort?

The speed indeed doesn't look right. The GitHub connection is great right now. I have 300Mbps network and the download speed can up to 2MiB/s for me. I am not sure if there is something between you and GitHub. You could try again with CARGO_HTTP_DEBUG=true and CARGO_LOG=cargo::ops::registry=trace environment variables, and --verbose flag to see if anything relevant happen.

Also, how is the speed when you just git clone https://github.com/rust-lang/crates.io-index.git? CARGO_NET_GIT_FETCH_WITH_CLI=true did use something to git fetch CLI, so I guess it won't help much as you've already tested it.

Otherwise you could try using sparse protocol, whose instruction is described in #11014 and will be the default for index fetch.

There is nothing relevant here, the only interesting bit is I am connected to the other side of the world. I will try sparse protocol thank you.

I dont know how but protocol worked @weihanglo . Thank you!
