### Why Preconnect Helps

`preconnect` pays off when a resource lives on a third-party origin: it moves the connection setup (DNS, TCP, TLS) off the critical path, so the request can start as soon as the resource is discovered. Step through the scenarios to compare connection reuse across HTTP versions and see what `preconnect` saves:

<Demo
src="/demos/network-waterfall.html"
title="Interactive network waterfall comparing HTTP/1.1 with Connection: close, HTTP/1.1 keep-alive, HTTP/2, and HTTP/2 with preconnect"
caption="Switch between HTTP/1.1, keep-alive, HTTP/2, and HTTP/2 + preconnect to compare how each affects the request waterfall."
heightKey="netWaterfallHeight"
