Enable HTTP/2 or HTTP/3

Modern HTTP protocols significantly reduce the impact of latency and allow multiple resources to be downloaded simultaneously over a single connection, leading to much faster page loads.

Quick Reference

• Enable HTTP/2 or HTTP/3 for request multiplexing
• Eliminate the need for resource concatenation
• Reduce overhead with header compression

Check

Verify that the server is serving resources over HTTP/2 or HTTP/3 using browser DevTools or online checkers.

Fix

Enable HTTP/2 or HTTP/3 in your web server (Nginx, Apache) or via a CDN/load balancer.
