Requests initiated by <link rel="preload"> or Early Hints are now displayed with a visual indicator in the Network request table.

Request labels in the Network Waterfall chart showing Preload requests with a visual indicator.

Request table with preload labels for hero image and CSS resources.

Preload and early hints help to improve page performance by hinting to the browser which requests are critical to render primary content quickly.

By carefully employing these techniques you can ensure that essential resources like hero images, CSS or Fonts are prioritised, leading to faster Largest Contentful Paint (LCP) and less layout shifts (CLS).

Using the Network request table, you can now quickly identify these requests and ensure that essential resources are prioritised accordingly.
