Starting from Rust’s Version 1.68, a game-changing improvement was introduced in Cargo with the introduction of the Sparse-Index protocol. This new approach replaces the traditional Git method, to using HTTPS for interaction with the registry (Artifactory in our case).
The switch not only boosts performance significantly but also opens the door for proxy use with remote repositories, giving you more control over index database connections.
