Based on informal benchmarking of running various implementations over large chunks of CSS containing only very simple style rules and declarations, I got the following best run numbers:

  • sassc: 1.439s
  • Dart Sass: 2.301s
  • Ruby Sass with a hot cache: 15.023s
  • Ruby Sass without caching: 18.488s

Based on these numbers, Dart Sass is approximately:

  • 1.6x slower than libsass
  • 6.5x faster than Ruby Sass with a hot cache
  • 8x faster than Ruby Sass when it has to parse as well
