Rust will frequently build code that will run in a comparable number of cycles, but can often run even faster as soon as you introduce concurrency. Safety isn't just some crutch to lean on instead of simply being really, really careful in C. Concurrent apps need a lot of guarantees for memory safety, and it takes a lot of mental energy to figure out how safe you really are. C devs often go overboard and do more than is necessary as a result.
