Ruby Racing: Challenging Ruby Methods
summary
Claims that some Ruby reimplementations beat their C counterparts and shows which methods actually improve, which fail (sample fails, sort is tricky, unique and max/min succeed). Benchmarks use a simple timing loop run 50,000 times so numbers are empirical but input‑sensitive. Implementations favor low‑level while loops and manual iteration over each to remove C-layer overhead. Results power an open source project and demo game called Ruby racer, with clear caveats about edge cases, benchmarking choices, and what “faster” actually means.
