Rust Compiler Performance Triage

This was a fairly negative week for compiler performance, with regressions overall up to 14% on some workloads (primarily incr-unchanged scenarios), largely caused by #101620. We are still chasing down either a revert or a fix for that regression, though a partial mitigation in #101862 has been applied. Hopefully the full fix or revert will be part of the next triage report.

We also saw a number of other regressions land, though most were much smaller in magnitude.

Triage done by @simulacrum. Revision range: 17cbdfd0..8fd6d03

See the full report for more details.

Call for Testing

An important step for RFC implementation is for people to experiment with the implementation and give feedback, especially before stabilization. The following RFCs would benefit from user testing before moving forward:

  • No RFCs issued a call for testing this week.

If you are a feature implementer and would like your RFC to appear on the above list, add the new call-for-testing label to your RFC along with a comment providing testing instructions and/or guidance on which aspect(s) of the feature need testing.

Approved RFCs

Changes to Rust follow the Rust RFC (request for comments) process. These are the RFCs that were approved for implementation this week:

Quote of the Week

At the #LinuxPlumbers Rust MC: "I'm Matthew Wilcox, I'm one of the authors of the NVMe spec, I'm the one who suggested you make an NVMe driver to demonstrate the value of Rust. You have succeeded beyond my wildest expectations. These performance numbers are phenomenal."

Josh Triplett paraphrasing Matthew Wilcox as spoken at the Linux Plumbers Conference Q&A session

Thanks to Josh Triplett for the self-suggestion!
