I am using a drop down in my every scene .By which i can select scene and go to that…But swapping between scenes take large time to load…Code i am using to change scene is given below

public class Loadscene : MonoBehaviour
{

    public Dropdown dropdown;
  
    void Update()
    {
        
        //Add listener for when the value of the Dropdown changes, to take action
        dropdown.onValueChanged.AddListener(delegate
        {
            DropdownValueChanged(dropdown);
        });
    }
    void DropdownValueChanged(Dropdown change)
    {
        SceneManager.LoadScene(change.value);
    }
}

How will the loading speed be increased?

Update runs every FRAME, you don’t want to add an event listener every frame.
Once is enough.

 void Start()
 {
     //Add listener for when the value of the Dropdown changes, to take action
     dropdown.onValueChanged.AddListener(delegate
     {
         DropdownValueChanged(dropdown);
     });
 }

Remove update method.
