Стресс-тестирование веб-приложения и создание программы тестирования Windows, которая раскручивает несколько потоков и отправляет веб-запрос на каждый из них.

Проблема в том, что я получаю следующий вывод:

01/09/09 11:34:04 Starting new HTTP request on 10
01/09/09 11:34:04 Starting new HTTP request on 11
01/09/09 11:34:04 Starting new HTTP request on 13
01/09/09 11:34:05 Starting new HTTP request on 14
01/09/09 11:34:05 Starting new HTTP request on 11
01/09/09 11:34:05 11 has finished!

01/09/09 11:34:06 Starting new HTTP request on 14
01/09/09 11:34:06 14 has finished!

какой вид там выглядитМаксимум 5 потоков, даже если я создаю 100 как так:

int numberOfThreads = Convert.ToInt32(txtConcurrentThreads.Text);

    List workers = new List();

    for (int N = 0; N < numberOfThreads; N++)
    {

        BackgroundWorker worker = new BackgroundWorker();
        worker.DoWork += new DoWorkEventHandler(worker_DoWork);
        worker.RunWorkerCompleted += new RunWorkerCompletedEventHandler(worker_RunWorkerCompleted);
        workers.Add(worker);
    }


    foreach(BackgroundWorker worker in workers)
    {
        worker.RunWorkerAsync();
    }

Может ли кто-нибудь просветить меня о том, что происходит?

Спасибо

РЕДАКТИРОВАТЬ: Если, как предложено, я сплю 5 секунд, а не httpwebrequest, то я получаю больше потоков, но не так много, как я ожидал:

Похоже, яЯ получаю только 2 потока, начинающихся каждую секунду, что мне кажется очень медленным. Я полагаю, что Console.WriteLine может быть проблемой?

РЕДАКТИРОВАТЬ: я установил

ThreadPool.SetMinThreads(100, 4); 

а также

System.Net.ServicePointManager.DefaultConnectionLimit = 100;

и получил следующие результаты:

01/09/09 14:00:07 Starting new HTTP request on 11
01/09/09 14:00:07 Starting new HTTP request on 81

так что смог одновременно вытолкнуть множество веб-запросов. Которая, казалось, стояла в очереди (обращаясь к серверу STA COM +), так чтоЭто то, что я ожидал.

Спасибо за вашу помощь
