Load testing via predefined number of threads

Wrote a short class for use with a load test. Probably it could be useful to someone else:-)

The class basically initiates e.g. 100 threads, and through a predefined delegate some method can be called more or less simultaneously from all of the threads.

Please remember that the .NET runtime allocates 1 MB ram to each thread. Hence you will get an OutOfMemory Exception if you attempt to initialize more threads than the memory available on your client can handle (1.000 threads ~ 1GB memory).

How to use the LoadTest

    class Program
        static void DoWork()
        static void Main(string[] args)
           LoadTest load = newLoadTest(100, DoWork);

LoadTest Code

using System;
using System.Collections.Generic;
using System.Text;
using System.Threading;

namespace LoadTest
    public delegate void TestMethod();
    public class LoadTest
        static TestMethod m_TestMethod;

        static List m_ThreadWaitEvents = new List();
        Int32 m_NumberOfThreads = 0;

        static void baseTestMethod()
            //Reference m_ThreadWaitEvents
            AutoResetEvent threadWaitEvent = new AutoResetEvent(false);
            //Invoke the test method

        public void Start()
            foreach (AutoResetEvent e in m_ThreadWaitEvents)

        public LoadTest(Int32 numberOfThreads, TestMethod testMethod)
            m_TestMethod = testMethod;
            m_NumberOfThreads = numberOfThreads;

            //Initialize threads
            for (Int32 t = 0; t < m_NumberOfThreads; t++)
                Console.WriteLine("Waiting. Thread " + t + " initiated.");
                Thread thread = new Thread(baseTestMethod);
            //Wait until all threads are initialized and references threadWaitEvent
            while (m_ThreadWaitEvents.Count < m_NumberOfThreads)
                Console.WriteLine("Initializing. " + m_ThreadWaitEvents.Count.ToString() + " of " + m_NumberOfThreads.ToString() + " threads started.");
