 ### Rust Compiler Performance Triage
 
-<!-- Perf results go here -->
+This week saw a lot of activity both on the regressions and improvements side. There was one large
+regression, which was immediately reverted. Overall, the week ended up being positive, thanks to
+a rollup PR that caused a tiny improvement to almost all benchmarks.
+
+Triage done by **@kobzol**.
+Revision range: [3e33bda0..c8a8c820](https://perf.rust-lang.org/?start=3e33bda0326586a6e1e34d0f5c060ca6d116e6a4&end=c8a8c82035439cb2404b8f24ca0bc18209d534ca&absolute=false&stat=instructions%3Au)
