Question: How do I use this to parallelize execution?

[Giszmo]

So I use gulp-html-minifier-terser on 875 html files which takes 4 minutes on my 24 core machine and uses one core I think.
I would hope to use your tool to get that down to much less. 10s maybe?

I'm not experienced with gulp but the task looks like this:

const htmlmin = require("gulp-html-minifier-terser");
gulp.task("minify", () => {
  return gulp
    .src("_site/**/*.html")
    .pipe(
      htmlmin({
        collapseWhitespace: true,
        removeComments: true,
        minifyCSS: true,
        minifyJS: true,
      })
    )
    .pipe(gulp.dest("_site"));
});

and applying parallel-transform I get to instantiate htmlmin but not to actually apply it to the files. What is missing here:

const htmlmin = require('gulp-html-minifier-terser');
const transform = require('parallel-transform');

gulp.task("minify", () => {
  return gulp
    .src("_site/**/*.html")
    .pipe(
      transform(24, {ordered:false}, (file, callback) => {
        htmlmin({
          collapseWhitespace: true,
          removeComments: true,
          minifyCSS: true,
          minifyJS: true,
        })
        callback(null, file)
      })
    )
    .pipe(gulp.dest("_site"));
});
