Plush's New Register-Based Interpreter Is Insanely Fast
A deep technical dive into rewriting the Plush programming language's interpreter from a stack-based design (like CPython) to a register-based design (like Lua), using a 64-bit instruction word. The rewrite, combined with a series of targeted optimizations (fused compare-and-branch, immediate shifts, constant deduplication, better branch layout, etc.), yields a geometric mean speedup of 1.94x over the old interpreter, with a median of 2.07x and a max of 3.37x across benchmarks. Benchmarked against CPython, CRuby, and Lua, Plush now outperforms Lua by 24-55% on select benchmarks and is fast enough to run Quake-level 3D rendering with texturing at interactive frame rates. Includes new install scripts for macOS/Linux/Windows and discusses future plans around object header sizing, TCP networking, and error handling.
