 Fusion was created with development and performance in mind, and was built with a focus on a lightweight, flexible system:
 
 * Initial DOMContentLoaded is fast. Asset URLs, translations, and experiments are not sent down in the application state in the page body; they are split per page-bundle, resulting in minimal HTML page size

 * Brotli compression is turned on by default, resulting in another 15-20% improvement on modern browsers (Edge, Chrome, Safari, Firefox, etc.)
 * [Bundle splitting](/docs/guides/routing#async-loading-routes) is extremely easy, allowing you to break down large applications into smaller parts and loading as necessary; in addition, we split translations, asset URLs and experiments along with each new bundle
 * Performance gains can easily be added into the system over time because of the way the core libraries and build tooling work; we already plan to improve our vendor bundle size even more, create ES2015-specific code bundles (no polyfill or babel-transpiled code) and Preact-fusion plugins (Preact is 87% smaller than React).
