Run some examples, and it looks like this "High-performance, real-time optimized, super-fast" language is ~ 10 times slower than luajit ~ 3 times slower than lua 5.4

Not bad for version 0.1.0. lua(jit) is no slowpoke and has had decades of performance improvements.

Where do you get these numbers from? Looking at https://github.com/Beariish/bolt/blob/main/doc/Bolt%20Performance.md https://github.com/Beariish/bolt/blob/main/doc/Bolt%20Perfor... doesn’t seem to support these numbers.

With this and https://github.com/Beariish/bolt/blob/main/doc/Bolt%20Performance.md https://github.com/Beariish/bolt/blob/main/doc/Bolt%20Perfor..., it is indeed confusing without testing it out myself. That said, somehow I do not believe it is faster than LuaJIT. We will see.

  I used brainfuck interpreter https://github.com/Beariish/bolt/blob/main/examples/bf.bolt https://github.com/Beariish/bolt/blob/main/examples/bf.bolt vs lua / luajit implementations from https://github.com/kostya/benchmarks https://github.com/kostya/benchmarks Just checked with nbody: - still 10 times slower than luajit - 2 times slower than luajit -joff - but 20% faster than lua 5.4 - but uses 47 Mb RAM vs 2.5 Mb for lua/luajit

    I appreciate the followup here. The brainfuck interpreter isn't meant to be a benchmark notably, it's a naive implementation for the sake of the example. I did spot some poor code in the Bolt version of nbody that can be changed (the usage of `.each()` in the hot loop is creating loads of temporary iterators, that's the memory difference.) luajit -joff does perform better even with this change, but I observe closer to 15% than a 2x difference

      for nbody 500000 on my i5-9300H CPU @ 2.40GHz - 487.41 millis / 2364 kb ram for luajit -joff - 770.17 millis / 41712 kb ram for bolt 770.17 / 487.41 ~~ 1.58 cpu, not 2x, but not 15% either 41712 / 2364 ~~ 17.64 ram

They at least clarified it by saying "outperforming other languages in its class". It's a slow class so the bar is low.
