C#中主线程和其他线程的基准测试

我遇到了一个问题，要演示使用单线程和多线程执行函数的基准测试。我在这儿干什么？如果是，我如何在不使用Join（）的情况下做到这一点。如果没有，建议我。

代码

class Threading1 
{
  static void Main (string[] args) 
  {
     Stopwatch timerMain, timerThreads;
     // Main thread 
     timerMain = Stopwatch.StartNew ();
     func1();
     func2();
     func3();
     timerMain.Stop ();
     Console.WriteLine ("Time taken for Main thread: " + timerMain.ElapsedMilliseconds);
     // Other threads
     Thread t1 = new Thread (() => Threading1.func1 ());
     Thread t2 = new Thread (() => Threading1.func2 ());
     Thread t3 = new Thread (() => Threading1.func3 ());
     timerThreads = Stopwatch.StartNew ();
     t1.Start(); t1.Join();
     t2.Start(); t2.Join();
     t3.Start(); t3.Join();
     timerThreads.Stop ();
     Console.WriteLine ("Time taken for Other threads: " + timerThreads.ElapsedMilliseconds);
  }
  // Find maximum value in an array
  static void func1() 
  {
    // Code here. 
  }
  // Find minimum value in an array
  static void func2()
  {
    // Code here. 
  }
  // Find average value of an array
  static void func3()
  {
    // Code here. 
  }
}

输出

Time taken for Main thread: 44
Time taken for other threads: 10

timerThreads = Stopwatch.StartNew();
var t1 = Task.Run(() => Threading1.func1());
var t2 = Task.Run(() => Threading1.func2());
var t3 = Task.Run(() => Threading1.func3());
Task.WaitAll(t1, t2, t3);
timerThreads.Stop ();
Console.WriteLine ("Time taken for Other threads: " + timerThreads.ElapsedMilliseconds);
