 ## Calls 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:

 ### Rust Compiler Performance Triage
 
-<!-- Perf results go here -->
+We missed triage last week due to some process issues, so this triage includes two weeks of data. The overall result is positive, due to parser optimizations ([#133793](https://github.com/rust-lang/rust/pull/133793)), trait solving optimizations ([#134501](https://github.com/rust-lang/rust/pull/134501), [#132325](https://github.com/rust-lang/rust/pull/132325)) and bumping the cc crate ([#134505](https://github.com/rust-lang/rust/pull/134505)), which [improved the performance](https://github.com/rust-lang/cc-rs/pull/1279) of C/C++ dependencies of the compiler.

 ### [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:
 
-<!-- Approved RFCs go here, use this format: * [Topic](URL) -->
-<!-- or if none were approved this week, use: * *No RFCs were approved this week.* -->
-<!-- * []() -->
