Unity3D的Delegate和SendMessage的性能差测试，以及Delegate在多线程使用要注意的小问题_nativeunitysendmessage 在哪个线程

一、回顾前面写的关于Delegate的消息传送优化文章，http://blog.csdn.net/chiuan/article/details/7883449 

下面的代码是做一个简单的Delegate和SendMessage之间的优化性能差距测试：

using UnityEngine;
using System.Collections;
/// <summary>
/// Delegate basic.
/// just test Delegate && SendMessage ..
/// 
/// By Chiuan 2012.8
/// </summary>
public class DelegateBasic : MonoBehaviour {
	
	//define my delegate statement.
	public delegate void MyDelegate(string arg1);
	
	//create my delegate object
	public MyDelegate myDelegate;
	
	//need some values to debug time spent.
	bool isStart;
	float timeStart;
	int count;
	
	bool isStartSendMessage;
	
	// Use this for initialization
	void Start () {
		myDelegate += myFunciton1;
		//myDelegate += myFunciton2;
	}
	
	// Update is called once per frame
	void Update () {
		if(isStart )
		{
