 ### Rust Compiler Performance Triage
 
-A week of mostly rather small changes with many regressions being hard to diagnose. The largest regression comes from the introduction of a new future (desugaring `.await` into a call to `IntoFuture::into_future`). This was deemed acceptable as it only seems to have a negative impact in stress test situations where async/await is used more than one would normally expect. Unfortunately this does mean regressions beat out improvements this week.
+This week's report started with 6 regressions; after eliminating truly obvious noise, we are left with just 2 minor regressions. Of the cases that regressed, I think the only interesting one is keccak (regressed by 1.73% in PR #91549). But don't be too depressed: keccak was also improved up to 23% by PR #85013 (!); thanks to @**simulacrum** for that PR.
