Re: funtion taking time to return Callback

I changed my application to use dwr 2.0.5. But still the same issue.
I think I dont have any delay in client side rendering (by the way am using
Firefox).
I have kept a timer before the function

StrandSummary.buildStrandSummary(objParametersBD,
      function(objSummary){
           objObjectiveSummary = objSummary;
           displayStrandSummary();
});

and after "function(objSummary)". My problem is it is taking some 20sec of
time to return me the callback function. Is that having more java beans is
creating problem. (I feel this should not be)

Thanks,
Rizwan
