Reducing HTTP Requests

No matter if it's CSS, JavaScript, or images: every asset that a browser has to download causes a performance hit. Even when a file's size is small, the transfer itself comes at a cost.

Keeping this overhead in mind means that every request counts, no matter how little data we're dealing with.

Less HTTP Requests, Faster Loading

Delivering Files Faster

Delivering few and small files is one important part of optimizing your website. But for really good performance, you should also think about how and from where your assets are delivered.

Learn how HTTP caching, Gzip compression, additional asset domains and CDNs help to speed up your pages.
