Unlike Python it scales with cores perfectly, which makes sense given that’s what BEAM is designed for, but the baseline cost of operations is in the same group

Unlike Python it scales with cores perfectly, which makes sense given that’s what BEAM is designed for, but the baseline cost of operations is in the same group. https://benchmarksgame-team.pages.debian.net/benchmarksgame/box-plot-summary-charts.html https://benchmarksgame-team.pages.debian.net/benchmarksgame/... It’s a bytecode-interpreted language. If it were JIT and statically typed we would have seen drastically different results. Also JIT output being slower than static compilation is a myth. When compilation happens does not dictate the kind machine code the compiler can produce (mostly, compiler throughput and JIT-time optimizations do influence this, but are not a strict limitation).

Erlang is JIT compiled since 2021. Grandparent is also correct in that it tends to be faster than Python et al. If we have a deeper look at the benchmarks [1][2], as long as there is no significant amount of bignum arithmetic (where both call C code) or standard IO involved [3] it's consistently faster than Python, and often by a large margin.

[2]: https://benchmarksgame-team.pages.debian.net/benchmarksgame/measurements/erlang.html https://benchmarksgame-team.pages.debian.net/benchmarksgame/... [3]: Standard IO goes through several indirections to make it work with remote REPLs; other forms of IO do not suffer from this.

  For your convenience: https://benchmarksgame-team.pages.debian.net/benchmarksgame/fastest/python3-erlang.html https://benchmarksgame-team.pages.debian.net/benchmarksgame/... > no significant amount of bignum arithmetic There is none shown in the charts. There is none shown elsewhere apart from where aribitrary precision arithmetic is shown explicitly: pi-digits.

    The memory taken and timeouts for Erlang are concerning in those benchmarks. And this is when compared to Python!

      Perhaps when programs written for pre-R12 are now at R27.
