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
}
}
}
}
}
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);
}
}
}

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。
