3.8.5

Improved Not available yet

UPDATE: Updated PHP and WordPress recommendations

Additionally, using requestIdleCallback to schedule the prerendering logic to run when the browser is idle can ensure that the user's experience is not impacted by the prerendering process.
UPDATE: Used the performance.now() function to measure the time it takes to execute the prefetching logic. The prefetch_throttle_delay value is adjusted based on the measured performance, ensuring that the prefetching logic only runs when the browser is able to handle it without impacting the user's experience.
