网络流速度不规律答案

【问题标题】：Networkstream irregular speed网络流速度不规律
【发布时间】：2014-06-08 06:53:19
【问题描述】：

我正在编写客户端-服务器通信。客户端向服务器询问一些内容，然后服务器每隔几毫秒响应一次（在我的问题案例中为 50）。

我正在使用 TcpClient 连接客户端和服务器，并使用 BinaryWriter/Reader 在 TcpClient 流（网络流）上进行写入和读取。

我每 50 毫秒发送约 100 ko 数据（实际上我尝试发送），即约 2000 个月/秒。客户端和服务器通过 rj45 线连接，客户端防火墙被禁用。

我的问题是 BinaryWriter.Write(myString) 最少需要 5 毫秒，最多需要 2500 毫秒。所以我尝试将 TcpClient Send/ReceiveBufferSize 增加到 20MB（默认为 8MB）和 NoDelay = true，这比以前好一点（之前最多需要 5 秒），但还没有那么好。

写入是如此不规则的事实让我认为缓冲区已满，BinaryWriter 正在等待它清空一点所以在客户端我在流上执行 ReadString 然后在线程中处理数据但问题仍然存在在那里。

代码：

服务器端：

private void traitementEnvois() 
{
    while (true) 
    {
        //some processing and wait for data to send

        NetworkStream stream = Client.GetStream();
        using (BinaryWriter writer = new BinaryWriter(stream, Encoding.UTF8, true)) 
        {
            while (!_envoisATraiter.IsEmpty) //ConcurrentQueue for data to send                     
            { 
                String jsonAEnvoyer;
                _envoisATraiter.TryDequeue(out jsonAEnvoyer);
                if (jsonAEnvoyer != null) 
                {
                    Stopwatch chrono = new Stopwatch();
                    chrono.Start();
                    writer.Write(jsonAEnvoyer);
                    long elaspedMs = chrono.ElapsedMilliseconds;
                    chrono.Stop();
                    EcritureEvenement.loggerEvenement("written in " + elaspedMs, TypesEvenements.DEBUG, "EnvoiParClient.traitementEnvois"); //log the event
                }
            }
        }
    }
}

客户端：

private void traitementStreamServeur(TcpClient server) 
{
    NetworkStream stream = server.GetStream();
    BinaryReader reader = new BinaryReader(stream);
    while (true) 
    {
        if (stream.DataAvailable) 
        {
            String messageJson = reader.ReadString(); //read data from the stream
            new Thread(() => traiterMessageRecu(messageJson)).Start(); //process data
        } 
        else 
        {
            Thread.Sleep(10);
        }
    }
}

也许你的秒表包括流的刷新时间和内核时间的执行......

好的，我发现客户端的处理量很大。之前没有真正测试过，所以我不知道花了这么长时间。

线程中的过程大约需要 29 秒，在我评论数据过程后，日志如下所示：
