6.10 Text Compression

Introduction:

Compressing text-based resources minimises the total bytes sent over the network with no negative impact on the user, compression makes HTML, CSS and JavaScript smaller, so they download faster. It’s one of the most direct levers on the “optimise the size of data transferred” principle: the fewer bytes that have to move down the wire, the less energy the network and the end device spend doing it.

Tools: gzip, deflate, brotli or equivalent.
