Hi @jolaka9284_9458, Thanks for providing all these details. I was able to pinpoint the reason for the slow down and why it specifically happens on some crates and not others. This is related to some code that we have to determine when to point cargo to pull dependencies from ProGet vs crates.io. Specifically this comes from cargo's API specs for dependencies: registry — cargo metadata uses a value of null to indicate that the dependency comes from crates.io. The index uses a value of null to indicate that the dependency comes from the same registry as the index. When creating an index entry, a registry other than crates.io should translate a value of null to be https://github.com/rust-lang/crates.io-index and translate a URL that matches the current index to be null. As you can see, the value specified in the metadata is different than the value the index needs to return. In ProGet, we will return null if the package exists in the feed (including connectors) and https://github.com/rust-lang/crates.io-index if it does not. This is to support the case when ProGet is not used as a mirror and instead for only local crates. Unfortunately the use ProGet as a mirror option is stored only in the client config and is not sent to ProGet. This is the reason why crates with a lot of dependencies take longer to generate the index than ones that don't and why you'll occasionally get timeouts, but after the retry it works. We have some caching on this to help with performance, but it's not a forever cache. I'm going to work on some potential improvements for this and will let you know when I have a solution ready. Unfortunately, the only workaround we have for this currently is to use a package approval workflow (like our npm Package Approval blog article). Thanks, Rich
