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

    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.

    Outils peu convaincant. L'outil conserve toujours le fichier compressé même si ce dernier est supérieur en taille.

    Dommage :-/ ça automatise une partie du taf déjà.
  • Samuel Martin on 18 Aug 10
     
    Mouai, Eric n'a probablement pas fait de test, mais de mon côté mieux vaut utiliser à la main les outils "optipng, pngout, deflopt avec options" on obtient de bien meilleurs résultats. L'intérêt de l'outil réside dans l'interface à la limite
  • Éric D. on 18 Aug 10
     
    Non, je n'ai pas fait de test. Par contre j'ai vu que la correction du bug soulevé par Samuel est prévue. Après attention, on peut toujours obtenir de meilleurs résultats à la main avec ce genre d'outils, mais parfois au prix d'un temps cpu démesuré. Le propre de ces outils c'est de choisir des valeurs raisonnables et optimale pour le compromis efficacité/temps. Pour moi l'intérêt c'est surtout que c'est "déjà fait", donc pas besoin de chercher les bons paramètres pour le compromis optimal, de faire appel à image magik pour savoir quel outil utiliser en fonction du format et du nombre de couleurs, et de scripter tout ça soi même : c'est déjà fait. J'apprécie aussi qu'ils aient prévu une gui *et* une cli pour le même outil. C'est assez sympa.

    When I was at DrupalCon Denver I suggested that all production JavaScript should be minified. This seemed like something simple that I wouldn't get any push back on. After all, the major JavaScript packages do it and the performance recommendation tools all recommend it. I was wrong.

    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.

Cache compressed? or uncompressed? | High Performance Web Sites - 1 views

    My previous blog post, Cache them if you can, suggests that current cache sizes are too small - especially on mobile. Given this concern about cache size a relevant question is: If a response is compressed, does the browser save it compressed or uncompressed? Compression typically reduces responses by 70%.
