If you don’t know me yet, I have been working on ArkScript for nearly 6 years now. ArkScript is a scripting language in modern C++, running on a custom virtual machine (like Python or Lua), with the goal of having a syntax easy to learn and use, a C++ interface to embed it in programs, and decent performances (without trying to be as fast as Lua though, Mike Pall is a genius and did outstanding work on LuaJIT).\n

I finally found a better memory layout to store variables in ArkScript, and I got a 76% performance boost on the binary tree benchmark, and a 21% perf boost on Ackermann(3, 7) Who knew using a contiguous storage buffer could be beneficial? 🤡

I retraced all the performance improvements I applied to ArkScript through the last five years, with updated benchmarks, AND DAMN what a journey.
