Resource Counts
The number of separate resource files a page requests affects load performance, particularly for users without HTTP/2 or with high-latency connections. Pages with many individual CSS and JavaScript files generate more HTTP requests, increasing load time and Time to Interactive. These two checks identify pages with unusually high CSS or JavaScript file counts.
Too Many CSS Files
Warning
Page loads an unusually high number of CSS files — multiple HTTP requests slowing render.
Too Many JavaScript Files
Warning
Page loads an unusually high number of JS files — multiple requests and parse overhead.
