Comparing performance across Node versions and ARM vs x86

Tinybench 6.0: A Tiny, Simple Benchmarking Library - Uses whatever precise timing capabilities are available (e.g. process.hrtime or performance.now ). You can then benchmark whatever functions you want, specify how long or how many times to benchmark for, and get a variety of stats in return - it runs across multiple runtimes, too. GitHub repo.

Chris concludes: “Switching to arm64 is the easiest performance win you can get.” As always with benchmarks, your own results may vary.
