I suspect once the Erlang/OTP team squeezes all performance in the JIT, they will look into optimizing across modules, which will probably open up many new possibilities, but it requires rethinking some runtime primitives.
You’re an inspiration for many. Thank you.
I’m curious to know what your top 3 hopes for BEAM itself are for the coming years (in any area that you think would make it better).
1. The cross module optimizations I mentioned above 2. Have a WASM target for the runtime itself 3. Make it easier to ship single file executables with the whole VM
But they are really “nice-to-have”s. I have been a happy user for 15+ years!
Knowing what I know now, I would’ve tried to push for a threaded interpreter to get rid of the runtime overhead of dispatching altogether. I don’t know if they’ve changed the architecture of that module much since I left :-)
