c# - Networkstream不规则速度

转载作者：太空宇宙更新时间：2023-11-03 15:56:48

我正在编写客户端-服务器通信的代码。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（在我的问题情况下为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毫秒发送一次约100 ko的数据（实际上，我尝试这样做），即约2000 mo / s。客户端和服务器通过rj45线连接，并且客户端防火墙已禁用。

我的问题是BinaryWriter.Write（myString）最少需要5毫秒，最多2500毫秒。因此，我尝试将TcpClient Send / ReceiveBufferSize增加到20MB（默认值为8MB），并且NoDelay = true，这比以前要好一些（之前要花5秒钟），但还不算好。

编写是如此不规则的事实使我觉得缓冲区已满，BinaryWriter正在等待它清空一些，因此在客户端，我在流上执行ReadString，然后在线程中处理数据，但问题仍然存在。

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);
        }
    }
}

最佳答案

好的，我发现客户端的处理量很大。在那之前并没有真正测试过它，所以我不知道它花了这么长时间。

在我注释了数据过程之后，线程中的过程大约需要29秒，这是日志的外观：
