N'Service WCF utiliser plusieurs threads pour traiter les requêtes entrantes?

Comment puis-je m'assurer qu'un service WCF utilise des threads à partir d'un pool de threads pour traiter les messages entrants?

Au moment de la simple invocation de méthode comme " return null;' prend environ 45 secondes, tandis qu'une autre demande en cours de traitement

Voici comment j'ai annoté ma classe de service:

[ServiceBehavior(ConcurrencyMode = ConcurrencyMode.Multiple, InstanceContextMode = InstanceContextMode.Single)]
    public partial class MyService : IMyService {
...
}

Mais quand je regarde les processus dans le gestionnaire des tâches, il semble être l'utilisation d'un constant nombre de threads. Même sous charge.

public ActionResult SelectDatabase(string param)
        {
            if (!String.IsNullOrEmpty(param))
            {
            try
            {
                MyServicece svc = new MyService();
                Database[] dbsArray = svc.GetDatabases(param);
                if (depsArray != null)
                    ViewData["depsArray"] = depsArray;

                return View();
            }
            catch (Exception exc)
            {
                //log here                
                return ActionUnavailable();
            }
        }

Voici mon comportement en service:

Ici est de savoir comment je crée une instance de service:

ServiceHost myserviceHost = new ServiceHost(typeof(MyService), new Uri(String.Format("net.tcp://{0}/", _bindAddress)));
myserviceHost.Open();
Console.WriteLine(myserviceHost.BaseAddresses[0]);
