Counts the number of page resources (CSS, JS, images).
This check counts the total number of individual files (like CSS, JavaScript, images, fonts) that the browser has to request to fully render your page.
Each request adds overhead and can increase page load time, especially on mobile networks. A very high number of requests can indicate a performance bottleneck.
While not a problem in itself, a high number of requests often correlates with slower load times. Reducing requests by combining files (e.g., CSS or JS) can be an effective optimization strategy.
