NODE.JS 16 TO 25 BENCHMARKS: HOW PERFORMANCE EVOLVED OVER TIME

Summary from the TLDR Dev newsletter

RepoFlow benchmarked Node.js versions 16 through 25 and found that performance has been steadily improving, with Node 25 showing impressive gains for computation-heavy workloads like tight loops and numeric operations. They tested everything from HTTP throughput to JSON parsing to buffer operations on an M4 Mac. Real-world performance will vary depending on your app's I/O patterns, but if you're doing data transformations or heavy computation, upgrading to newer Node versions should give you noticeable speed improvements.
