Hello, thank's for the quick answer ! I tried with IE, FF and Chrome. The result is the same. I profiled the client with the Chrome plugin Speed Tracer : I thought there was no ambiguity. But I had a doubt because chrome is working strangely on my pc. I then created a simple restlet client in order to test : ClientResource resource = new ClientResource("http://127.0.0.1:8888/restlet/operations/byAccDate/start01102010/end10102010"); resource.get(MediaType.APPLICATION_JAVA_OBJECT_GWT).write(System.out);
There is no doubt : if i don't de-serialize, the performance is very good... The pb is on the client side... my first tests will be : 1/ desactivate every graphical update on the client side : done, no significant result (13s) 2/ de-serialize the json string result in gwt 3/ try the Google Chrome Frame you mentionned 4/ ? any suggestion ? Is there a way to improve the de-serialization with GWT ? Should I modify my objects ? Should I store the data corresponding to the "Operations" in tables / array (not very familiar with javascript...) Thank's !
