Why does my program (c#) take forever to get the post data from server using SelectNode with xml

So I have a HTTP post request going to the server then the server is responding back in sending me data about user like userID in xml format. Then I read in the information via this code.. But it takes a while to read in from the response. Anyone knows a faster way?

             //read response
            var xml = new StreamReader(response.GetResponseStream()).ReadToEnd();


            // XML TYPES
            XmlDocument xml2 = new XmlDocument();
            xml2.LoadXml(xml);
            // select data
            XmlNodeList info = xml2.SelectNodes("/UserInfo/");
            foreach (XmlNode u in info)
            {


                string id = u["id"].InnerText;
                string username = u["username"].InnerText;
                string money = u["money_owed"].InnerText;
                UID.Text = id;
                username.Text = username;
                OWED.Text = money;

            }

And I got a couple more things I select. Much appreciated for the help.
