+# Benchmarks
+
+To get an overview how the performance of WebAssembly compares to other implementations, some benchmarks were done.
+The used benchmark code is from the [Computer Language Benchmarks Game](https://benchmarksgame-team.pages.debian.net/benchmarksgame/index.html).
+
+Note that these are only micro-benchmarks. They test one very specific implementation of something, whereas a real program would use multiple or complete other things that aren't tested here.
+
+The benchmark sources can be found [here](https://github.com/bytedream/litbwraw/tree/main/lua-playground).
+
+### Environment
+
+Every benchmark runs 5 times and the final benchmark results are calculated from the average result of each run.
+All benchmarks are using NodeJS to execute them. NodeJS itself always has a performance/memory overhead as it needs to spin up a new V8 engine every time, which is the explanation why the base memory is so high.
+
+Host & OS:
+- Raspberry Pi 4, 2GB RAM
+- Raspberry Pi OS Lite, 64 bit, 2024-11-19
+
+Software:
+- Rust v1.85.0
+- NodeJS v23.7.0
+- Emscripten v4.0.4
+
+Tested Software:
+- WebAssembly (wasm); mlua v0.10.3
+- Fengari (fengari); fengari v0.1.4
