This repo contains correct benchmark for various tools.
Many benchmarks suck, because they don't align tasks the tool does. Car costs more than apple for good reasons, but many people compares price of apple and car.
To be fair, benchmarks are grouped base on their tasks.
Each directory contains simple description for tasks. (But don't expect too much, I don't like documenting stuffs)
npm i
npm run benchRun on MacBook Pro (13-inch, 2020, Four Thunderbolt 3 ports), 2.3 GHz Quad Core Intel Core i7, 32GB 3733 MHz LPDDR4X.
What really matters is parallel benchmark because it represents real word usages, assuming the build tool you are using is not a dumb.
Note: esbuild does not support es3 nor es5.
