    AsyncCallback GWT - 25 minute delay

      Hi all

      I am making a single Asynchronus call in GWT to the server which performs some work on the server and then returns back the results in the form of a List<String> which contains approx 50,000 entries.

      When the code returns to the on Success() there is a 25 minute delay. Could someone please suggest any performance improvements or things I might be doing wrong resulting in this delay?

      The code is as follows:

      public void openFileRpcCall(final String serverFileName){
           // 1. create the client proxy
           //MyServiceAsync fileOpenService = (MyServiceAsync) GWT.create(MyService.class);
           // 2. create an async callback to handle the result
           final AsyncCallback callback = new AsyncCallback(){
                //public void onSuccess(Object result) {
                public void onSuccess(Object result){// result Object - List<String>
                     System.out.println("in onSuccess for openFile()");
                     // do stuff here
                public void onFailure(Throwable caught) {
           // do more stuff

      Thanks for any suggestions
