I have just started playing around with Web Services.  I created a sample
Web Service and invoked a sample "Hello World" method call from my Win Forms
control running under an ASP.NET web page.  The time it takes to return the
result seems a little bit much.  It takes anywhere from 500 to 800
milliseconds to return a simple "Hello World" string message.  This is even
running it on localhost.  Is this normal for the request to take this long?
If not, what can I do to make it faster?

Here is an example of my calling logic:

     private void DoCall()
     {
           String ServiceText;
           ICredentials myCred;
           MyWebService TestService = new MyWebService();

          myCred = new NetworkCredential("userid","password");
          TestService.Credentials = myCred;

          ServiceText = TestService.HelloWorld();       // This call seems
very slow.
    }
