Hi, we uses __doPostBack in our application we feel it's too slow , is there any way to accelerate it?
The following is a JS code example from our application:
function CallServerFunction(command,arg) 
    { 
        var hiddenID = 'HiddenField1';
        var hiddenField = document.getElementById(hiddenID); 
        hiddenField.value = command + "," + arg; 
        __doPostBack(hiddenID,arg)     
    }

A post back will reload the whole page. It also posts all the view state data with it which means more traffic. Are you sure you need it? Or maybe a simple ajax call can do the job?

As you can see from the code, we use __doPostBack function to send a value to a server side code to act based on that value. Is there any faster alternative?

If you could include a javascript utility like jquery then you can pass the hidden field value to an asp.net pagemethod.  See the link below for how to set it up.

Can you use a standard Asp.net pagemethod call?

It's faster because it doesn't have to send and retrieve all of the forms data.  It will only send and receive what is necessary for the function call.  A postback will cause the browser to rerender the entire form where as a pagemethod will only affect the fields that you want it to affect.
