Hello World!

Using this project

This page prerenders a few links (to reduce the loading time to as near-zero as possible). Open DevTools, ensure "Disable cache" is ticked, go to the Console enable Preserve log and type "LCP", then install the Web Vitals Extension with console logging, and give the page a few seconds to prerender the links.

Click this link to go to index2.html with a VT and measure LCP.

Click this link to go to index3.html without a VT and measure LCP.

You should notice with VTs takes a little longer (180ms - 200ms for me) than without VTs (80ms - 180ms).
