描述

The JS-compiled version of Dart Sass hovers around 2.5x and 3x slower than when running on the Dart VM. Some slowdown is inevitable, but this seems extreme. We should put dedicated effort into profiling the JS output and optimizing hot spots.

研究方向
The issue requires identifying performance bottlenecks in the JavaScript compiled output of Dart Sass. Review the existing 37 comments for any profiling data or suggested hot spots. Investigate the Dart source code's compilation output, possibly examining the 'lib' directory and JavaScript generation logic. Look for any linked PRs or branches mentioned in the comments that attempted optimizations.
