Hi to all,
since I’ve enabled the push support in Vaadin (either streaming, long polling or websocket), I noticed that the loading of my web site has slowed down significantly (0.8s avg), looking firebug net panel I’ve seen that, when using polling the browser always makes GET calls to an address containing /UIDL which are very quick.
Since I’ve annotated my UI with the @Push annotation, every user interaction makes a POST call to an Atmosphere URL, which takes more time to complete.
Why Atmosphere is causing these issues?
Any suggestion will be kindly appreciated, because in production environment these performance issues are causing me many troubles.
