Number of HTTP requests

Many files = many requests = a slower start.

What it is

Every file (CSS, JS, image, font) is a separate HTTP request. A large number of small requests increases overhead, especially on a slower connection.

Why it matters

Many requests mean more connection setup and overhead. On HTTP/2/3 it's less painful, but combining and removing redundancy still helps.

How to do it

1Combine tiny CSS/JS files (a build bundler).
2Use CSS sprites or inline SVG for small icons.
3Remove unused libraries and external scripts.
4Switch to HTTP/2 or HTTP/3, which handle parallel requests better.

Conclusion

Fewer, larger files usually beat many small ones. Combine what you can, remove redundancies, and enable HTTP/2+. Together with compression and caching, this forms the basis of fast delivery.
