Checks if the server supports the modern HTTP/2 protocol for better performance.
This check verifies if your web server supports the HTTP/2 protocol, which is a major revision of the HTTP network protocol.
HTTP/2 is significantly faster and more efficient than its predecessor, HTTP/1.1. It allows for multiplexing (sending multiple requests over a single connection), header compression, and other features that dramatically reduce page load times.
Not using HTTP/2 means you're missing out on significant performance gains. Most modern servers support it, and it should be enabled.
