Your page has to make a very high number of individual requests to the server to load all of its resources (CSS, JS, images, etc.). Each request adds overhead and can slow down the page, especially on mobile networks. Reducing the total number of requests is a key performance optimization strategy.
A page that loads 10 separate small CSS files and 15 separate small JavaScript files.
Combine files where possible. Use a build tool to bundle your CSS and JavaScript files into fewer, larger files. For images, consider using CSS sprites for small icons. Also, remove any resources that are no longer needed.
Fewer network requests mean less waiting time and less overhead, allowing the browser to download and render your page more quickly. This is especially impactful on high-latency mobile connections.
This issue can affect your site's search engine rankings and user experience. Addressing it promptly helps ensure optimal performance and visibility in search results.
