You can get this working with Tokio if you know what you are doing.

However, I personally advise against it as I have found that deferring to the OS for scheduling results in poor thread affinity (your state gets bounced around threads unnecessarily).

You generally get better throughput by either running multiple fully isolated reactors (the seastar approach) or running a single reactor which only flags tasks as ready to be executed, and then use a work stealing thread pool to do the actual execution.

Both of these structures are easy to achieve with Tokio.
