> The other thing worth considering here, is that it is fair; there are benchmarks out there [1] that show other languages may have lower latency in some cases, but the overall fairness of the BEAM scheduler is better, and per above has less traps/footguns. This is a recurring topic in a lot of engineering problems: optimising for the best average case possible, versus optimising for the best worst case possible. Like e.g. a game that averages 200fps but has occasional dips to 20 fps versus a game that is rock-solid at 100fps and never dips. The absence of dips matters more than the peak performance.
