What you say is that Elixir is "very fast" when it comes to tasks when Elixir pretty much doesn't do anything, so it being fast or slow doesn't matter. Hardly a definition of "fast". But it is actually true for BEAM machine. It was never intended to be fast, it was intended for running many tasks at the same time (so that none of them starves others for any reason).
