Rust Compiler Performance Triage

  • 2020-11-24: 1 Regression, 2 Improvements, 2 mixed

This week saw landing of #79237 which by itself provides no wins but opens the door to support for split debuginfo on macOS. This'll eventually show huge wins as we can likely avoid re-collecting debuginfo while retaining support for lldb and Rust backtraces. #79361 tracks the stabilization of the rustc flag, but the precise rollout to stable users is not yet 100% clear.

Triage done by @jyn514 and @simulacrum.

4 regressions, 4 improvements, 2 mixed results. 5 of them in rollups.

Quote of the Week

Let’s be clear: We understand that we are net beneficiaries of the exceptional work that others have done to make Rust thrive. AWS didn’t start Rust or make it the success that it is today, but we’d like to contribute to its future success.

Matt Asay on the AWS Open Source blog

Thanks to Alice Ryhl for the suggestion.
