Rust makes it much easier to do complex performance optimizations safely, particularly those involving concurrency. The canonical example is the multi-threading of Servo’s CSS processor.

It’s not an automatic magic bullet, but in a world where humans are still writing the code, Rust’s feature set makes many performance optimizations much more practical.
