🏃♂️🏃♀️🏃 JS minification benchmarks
Benchmarks are gathered on the following minifiers:
📋 Results
- Each minifier is executed in its own process
- The measured time is an average taken from 10 consecutive runs
- Each table is sorted by smallest minified size
- Minzipped size measures how well the minified file compresses with Gzip
- Comments are not stripped because not all minifiers support this
