Stuttering / performance issue with certain JS scripts

Questions & Answers
1

Working on a very simple pong style game, I have two scripts which cause the game to skip / stutter for the first few seconds of the scenes loading up. If I remove these two scripts, the stuttering goes away. It seems to stabilize after 10-15 seconds and only happens when the level first starts. However, since this game is physics based and the ball is always moving, any skipping, stuttering or slowdown is visible.

I am seeing the stuttering issue on an iPhone 5 but it is not visible on the engine Game window. Using the free version of Unity, I do not have access to the profiler.

Any ideas why these two bits of script are causing stuttering issues?

Thank you

This is a countdown timer. When the timer reaches zero, the game advances to the next level.

//Countdown Timer (Visible)
			
var endTime : float;
var textMesh : TextMesh;
     
function Start()
{
    endTime = Time.time + 63;
    textMesh = GameObject.Find ("Text_Timer").GetComponent(TextMesh);
    textMesh.text = "63";
}    

function Update()
{
    var timeLeft : int = endTime - Time.time;
    if (timeLeft < 0) timeLeft = 0;
    textMesh.text = timeLeft.ToString();          
}
   
//End level and load win screen after X Seconds (Invisible)    	
var timeLimit : float = 63; // 1 minute timer
 
Invoke("NextMap", timeLimit);    
function NextMap() 
{
    Application.LoadLevel("Win");
}

This is a quit game button which takes the player back to the main menu.

private var ray : Ray;
private var rayCastHit : RaycastHit;
 
//Load Previous button
function LateUpdate ()
{
	//Load Previous Level		
		if(Input.GetMouseButtonDown(0))
	{
		ray = Camera.main.ScreenPointToRay (Input.mousePosition);
		
		if (Physics.Raycast (ray, rayCastHit))
		{
			if(rayCastHit.transform.name == "Text QuitToMenu")
			{
				Application.LoadLevel("L0.0 Menu");
			}				
		}  			
	} 		
}

Turns out, it was the 3D Text turning on and off. It was creating a texture right then that was causing the game to pause momentarily. I solved this by adding those letting in a preload area of the game.
