But it also reduces load on your server. While it does take some amount of computer power to compress files on the fly, you save much more power by having your server doing fewer things at once. It takes a lot less time to transfer files that are smaller. Your server is therefor, at any given time, maintaining far fewer open connections.

Automatisation de Yslow. La prise de conscience sur le sujet des performances web évolue.

Automatisation de Yslow

Beaucoup d’équipes ont désormais appliqué quelques recettes de base, ou ont au moins un item dédié dans la liste des choses à faire. Il reste toutefois à passer une phase d’industrialisation.
