BTW, many years ago, the author of Erjang told me that eventually Erjang will be faster than BEAM for running Erlang apps, b/c of all the investment that went into the JVM ecosystem. I'm not sure it's the case now (probably since nobody using Erjang in production). You are correct in describing the raw performance of BEAM, but I'm not sure it's relevant for a typical IO-bound Erlang/Elixir app. Also most large real-life apps would use NIFs written in a language capable generating native code, i.e. C/C++ or Rust.
