Elixir uses slow interpreted vm, you can't put it into the same high performance category and golang, java, c++ and rust can't do well on massively multicore systems on their own, you would have to fight them to do it, ditch idiomatic ideas and effectively build your own runtime and use your own concurrency model (not shared memory multithreading!). So they are more like every other language that is somewhat close to the primitives that OS and hardware provide, not actually well suited for the job itself.
