Magento 2 Quicklink module attempts to make navigations to subsequent pages load faster.

• Detects links within the viewport (using Intersection Observer)
• Waits until the browser is idle (using requestIdleCallback)
• Checks if the user isn't on a slow connection (using navigator.connection.effectiveType) or has data-saver enabled (using navigator.connection.saveData)
• Prefetches URLs to the links (using <link rel=prefetch> or XHR). Provides some control over the request priority (can switch to fetch() if supported).

Install using Composer.

composer require rafaelcg/magento2-quicklink
php bin/magento setup:static-content:deploy -f
php bin/magento cache:clean

After installation, it will be enabled by default. You can find the configuration into Stores > Configuration > General Web > Google Quicklink.
