Strong recommendation to look into ASP.NET Core with C#. It gives static typing, easy first-class concurrency, it runs on all platforms and now can be AOT compiled if that's your thing, if not - can still produce just a single executable if you choose to. Also its CLI is nice and similar to cargo. Naturally, you won't be having performance issues.
