I have two test apps that call my webservice with the exact same code in
each.  One is running in VS2003, the other in VS2005.  The 2003 version takes
1 second, the 2005 version takes 20-30 seconds.  It only takes that long on
the first call though, after that it too returns in 1 second.  The code is
very simple:

private void button1_Click(object sender, EventArgs e) {
   MyWebService n = new MyWebService();
   n.MyMethod();
   MessageBox.Show("done");
}

For what it's worth, the web service is a Java application but I don't think
that should matter should it?  Are there any known issues with calling web
services in Dotnet 2.0?  Any suggestions at all?
