Of course rust is not performance.
Rust is a programming language. Performance is a mix of programmer's ability, clever design and compiler optimizations.

Many supporting crates reinforced this. Rayon, Tokio (though not "performant", it was an improvement over naive impl), etc made jumping from hello world to parallel/concurrent execution pretty simple.
But I'm glad to see the downturn on that hype cycle.
async != performance
async == concurrency
Unless you face a specific kind of slowdown, concurrency, and therefore async (and therefore tokio) is not a panacea. Many do face that slowdown, so for many it is.
