Not sure i understand what the use case is. As soon as you start doing something on the event loop , you need some kind of way to perform the operation in another "thread" ( or goroutine or whatever). And then you start to need some kind of concurrency mechanism, and pay the price.

Stripping those mechanism to pretend the event handling is faster only works if you never intend to have some real computation performed. That's never true in practice... Or am i missing something ?

Not the OP but typically you resort to these tactics when you want to shave the last ms of the server's response time, and/or get that last 1000 requests/s/core performance. You have a "fast path" that is simple and event driven and hand off operation processing to regular threads for the (less frequent) more complex operations.

So you're not missing anything.

Aren’t you losing a lot of the benefit by using a GC’d language in the first place?
