 ### Rust Compiler Performance Triage
 
-<!-- Perf results go here -->
+A busy week in compiler performance, but fortunately improvements outweighed regressions. The biggest improvements came from @nnethercote's work on making the decoding of `SourceFile::lines` lazy which significantly cuts the costs of decoding crate metadata. The biggest regressions came from the removal of json handling in `rustc_serialize` which has been a multi-month effort to improve the maintainability of json (de-)serialization in the compiler.
 
-### Call for Testing
+Triage done by **@rylev**.

+### [Call for Testing](https://github.com/rust-lang/rfcs/issues?q=label%3Acall-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:
 
-<!-- Pre-Stabilization RFCs go here -->
+* [RFC: 'C-unwind' ABI](https://github.com/rust-lang/rfcs/pull/2945)
+    * [Testing instructions](https://github.com/rust-lang/rfcs/pull/2945#issuecomment-1134003542)
+
+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](https://github.com/rust-lang/rfcs/commits/master)
+
+Changes to Rust follow the Rust [RFC (request for comments) process](https://github.com/rust-lang/rfcs#rust-rfcs). These
+are the RFCs that were approved for implementation this week:
+
+* *No RFCs were approved this week.*

+### Final Comment Period

+which are reaching a decision. Express your opinions now.
