After changing the version to beta, I was able to see a significant difference. When running rust-analyzer in vscode with rustup version 1.24.1 it took a very long time than usual. With version 1.24.2 beta it took me the usual time again. Maybe rust-analyzer uses rustup internally.

Thank you for addressing this issue and letting us know about the beta testing. I asked one of the users who reported a duplicate issue #2764 on Raspberry Pi 3 to join the beta testing. So far, so good; he verified that Rustup v1.24.2 beta can install the latest Rust stable tool chain without problem.
