On annonce des gains au final de 30% à 60%, cela semble assez important. Est-ce vraiment intéressant dans tous les cas ?. C'est un besoin pour les sites à gros traffic/ non optimisé / avec du contenu 'peu dynamique". Comment Fasterize actualise t'il sa propre version , uniquement lorsque le client demande une url ? Il serait intéressant d'avoir un peu de détail sur l'échange entre fasterize et le serveur.

Why is getElementsByTagName() faster that querySelectorAll()? - 4 views

shared by Thomas Bassetto on 29 Sep 10 - No Cached

getElementsByTagName("a") is faster than querySelectorAll("a") in nearly all browsers. There's one very important difference between these two methods, and it's not that one accepts only a tag name and the other accepts a full CSS selector. The big difference is in the return value: the getElementsByTagName() method returns a live NodeList while querySelectorAll() returns a static NodeList. This is extremely important to understand.

en fait, la création de la liste d'éléments est 90% plus rapide avec getElementsByTagName par contre ça peut être compensé par les accès aux propriétés, plus rapides avec la liste statique retournée par querySelectorAll : http://jsperf.com/access-to-nodes-via-queryselectorall-vs-getelementsbyta/2 donc rien d'absolu, ça dépend de chaque code

Are WebSockets faster than AJAX? ...with latency in mind? - Peterbe.com - 0 views

ajax websockets

shared by Laurent Paoletti on 22 Apr 12 - No Cached

Laurent Paoletti on 22 Apr 12

The advantage with WebSockets (over AJAX) is basically that there's less HTTP overhead. Once the connection has been established, all future message passing is over a socket rather than new HTTP request/response calls. So, you'd assume that WebSockets can send and receive much more messages per unit time.

This week begins face to face meetings at the IETF on how to approach HTTP 2.0 and improve the Internet. How the industry moves forward together on the next version of HTTP - how every application and service on the web communicates today - can positively impact user experience, operational and environmental costs, and even the battery life of the devices you carry around.
