title: Gulp speed up SASS compilation
body: <p>I'm using Gulp with livereload to compile my sass. Since I've added Compass to my build each time I make a change the sass task takes up to 5 seconds to complete.</p>
  
  <p>I've read about various cache plugins such as <a href="https://github.com/wearefractal/gulp-cached" rel="nofollow">gulp-cached</a> but I can't get it to work. When I add gulp-cached the compliation times goes down to about 20ms and it only processes the changed sass partial but the rest of the sass task doesn't run.</p>
  
  <p>Here is my SASS task</p>
  
  <pre><code>gulp.task('styles', function () {
      return gulp.src( paths.scss )
          .pipe( cache( 'sass' ) )
          .pipe( scss( options.scss ).on( 'error', gutil.log ) )
          .pipe( autoprefix( options.autoprefix ) )
          .pipe( gulp.dest( dests.css ) )
          .pipe( livereload() )
          .pipe( notify( { message: 'CSS task complete.' } ) );
  });
  </code></pre>
  
  <p>And my full gulpfile can be found here: <a href="http://hastebin.com/oxuxegayoj.coffee" rel="nofollow">http://hastebin.com/oxuxegayoj.coffee</a></p>
  
  <p>Should cache plugins work with sass compilation or is this how it should work?</p>
