@deafbeef @adam_chal yeah, this is the well-known benefit of async over threads. My question is more whether there is a fundamental change in the programming logic or if there is a real-life performance improvement or capacity improvement of the implemented system

@adam_chal would that be meaningfully different to running multiple OS threads on one core?

When teaching async Rust, there is often an emphasis on concurrency vs parallelism. Why? Why is it considered more important here than when programming in threads? IMO it applies equally in both systems, it's just apparent in different ways
