This is to be expected because Cargo is still using libgit2 (a
not-very-performant Git implementation) to fetch index repositories.
Depending on your system's single-core performance, this can take up
to an hour on low-power systems.

Usually, I manually update the index repositories. You can try the
following commands:
cd ~/.cargo/registry/index/github.com-1ecc6299db9ec823
git remote add origin https://github.com/rust-lang/crates.io-index
git fetch --all
git gc --aggressive # (optional, repacks Git repository, significantly
optimizes disk usage, but can take half an hour with all CPU cores at
100%)
