title: Unity Scene loading times are extremly long
body: <p>I'm pretty new to Unity so not much excperience with the IDE.
  I'm developing a pretty basic application, a Login and a dashboard with some basic UI elements.</p>
  
  <p>The problem i encounter is when i try to switch scenes. So from the LoginScene to the Dashboard scene it can take up to 20 seconds.
  There isn't even much logic that the script has to run.
  This is way to long in my opinion, someone knows how to optimise my code or at least knows what i'm doing wrong ? </p>
  
  <p>This is the code for checking correct user and changing scene.</p>
  
  <pre><code>// Start is called before the first frame update
  void Start()
  {
      Screen.orientation = ScreenOrientation.Portrait;
  }
  
  // Update is called once per frame
  void Update()
  {
      //get values from inputfields
      emailString = email.GetComponent&lt;InputField&gt;().text;
      passwordString = password.GetComponent&lt;InputField&gt;().text;
  
      btnLogin = login.GetComponent&lt;Button&gt;();
      btnLogin.onClick.AddListener(ValidateLogin);
  }
  
  private void ValidateLogin()
  {
      if (emailString.Trim() == "aa" &amp;&amp; passwordString.Trim() == "aa")
      {
          print("login succeeded!");
  
          SceneManager.LoadScene(1);
      }
      else
      {
          print("wrong credentials");
      }
  
  }
  </code></pre>
  
  <p>Btw: The number 1 is the reference to my next scene, the Dashboard scene.</p>
