Above: the time to do a production bundle of 10 copies of the
three.js library from scratch using default settings, including
minification and source maps. More info here.

Our current build tools for the web are 10-100x slower than they
could be. The main goal of the esbuild bundler project is to bring
about a new era of build tool performance, and create an easy-to-use
modern bundler along the way.

Major features:

  * Extreme speed without needing a cache
  * ES6 and CommonJS modules
  * Tree shaking of ES6 modules
  * An API for JavaScript and Go
  * TypeScript and JSX syntax
  * Source maps
  * Minification
  * Plugins

esbuild a try.
