每秒接受的SocketAsyncEventArgs和second

Question

我正在使用SocketAsyncEventArgs，并且我每秒只能执行几次接受(我不知道为什么)。

如何最大化每秒接受的数量？我应该多次调用Accept(null)吗？

代码:在侦听套接字上调用Listen之后，我调用了Accept(null)，这是我的代码：

void Accept(SocketAsyncEventArgs acceptEventArg)
{
    if (acceptEventArg == null)
    {
        acceptEventArg = new SocketAsyncEventArgs();
        acceptEventArg.Completed += AcceptCompleted;
    }
    else
    {
        // socket must be cleared since the context object is being reused
        acceptEventArg.AcceptSocket = null;
    }

    bool willRaiseEvent = _listener.AcceptAsync(acceptEventArg);
    if (!willRaiseEvent)
    {
        Accepted(acceptEventArg);
    }
}

void AcceptCompleted(object sender, SocketAsyncEventArgs e)
{
    if (_onAccepted != null) _onAccepted(e);
}

void Accepted(SocketAsyncEventArgs e)
{
    if (!e.AcceptSocket.Connected) return;

    //1
    var acceptSocket = e.AcceptSocket;
    var readEventArgs = CreateArg(null, e.AcceptSocket, null);

    bool willRaiseEvent = true;
    if (acceptSocket.Connected)
        willRaiseEvent = acceptSocket.ReceiveAsync(readEventArgs);

    //2
    Accept(e);

    //3
    if (!willRaiseEvent)
    {
        Received(readEventArgs);
    }
}

默认情况下有连接限制。可以使用DefaultConnectionLimit http://msdn.microsoft.com/en-us/library/system.net.servicepointmanager.defaultconnectionlimit.aspx对其进行更改
