 ### Rust Compiler Performance Triage
 
-<!-- Perf results go here -->
+Difficult week to interpret, because a positive change in [#145910](https://github.com/rust-lang/rust/pull/145910) skewes the results more negative in our benchmarks. Overall result is probably still slightly negative, because there's more work from added features. On the other hand, we also have a nice improvement in reducing the number of query dependencies in compiler's tracking system in [#145186](https://github.com/rust-lang/rust/pull/145186).
