Implemented performance improvement for Magento.

• Preload https://developer.mozilla.org/en-US/docs/Web/HTML/Attributes/rel/preload
• Prefetch https://developer.mozilla.org/en-US/docs/Glossary/Prefetch
• Preconnect https://developer.chrome.com/en/docs/lighthouse/performance/uses-rel-preconnect
• Lazy loading https://developer.mozilla.org/en-US/docs/Web/Performance/Lazy_loading
• Server Push https://www.smashingmagazine.com/2017/04/guide-http2-server-push

All these concepts were implemented in the pages through a plugin in HttpResponse. We search via regex in the html of the pages and implement the concepts mentioned above.

For preconnect you might add new external links as needed in Stores > Configuration > The IT Nerd > Performance > Additional Preconnect Entries. By default we added these url's with preconnect:

• https://fonts.gstatic.com
• https://fonts.googleapis.com

For Server push you might add new resources as needed in Stores > Configuration > The IT Nerd > Performance > Server Push > Aditional Images.
