[网络协议]jmeter tcp sampler 测试网速

1 下载Jmeter

https://mirror-hk.koddos.net/apache//jmeter/

2 开启Jmeter

3 添加线程组

4添加 TCP sampler

5添加View Tree

设置１个线程不断循环?

6设置线程组??

７设置Tcp sampers

?设置eolvalue=9，十进制，当tcp sampler 接收到服务器回复字节９的时候，开启下一次循环。发送21,539 字节。

?8开启测试

点击绿色三角形开始发送，点stop六边型停止

９服务器端java代码入下?

package com.suncreate.testSocket;

import java.io.InputStream;
import java.io.OutputStream;
import java.net.*;
import java.util.Arrays;
public class SocketServer {
    public static void main(String[] args) throws Exception {
        // 监听指定的端口
        int port = 55533;
        ServerSocket server = new ServerSocket(port,50, InetAddress.getByAddress(new byte[]{(byte)172,16,37,(byte)162}));
        System.out.println("waiting");
        Socket socket = server.accept();
        // 建立好连接后，从socket中获取输入流，并建立缓冲区进行读取
        InputStream inputStream = socket.getInputStream();
        OutputStream outputStream=socket.getOutputStream();
        byte[] bytes = new byte[1024];
        int len=0,total=0;
        long second=0,start=System.currentTimeMillis();
        while ((len = inputStream.read(bytes)) != -1) {       
            System.out.println(len);
            total+=len;
            second= (System.currentTimeMillis()-start)/1000;
            if(second!=0)
                System.out.println(total/second);       
            System.out.println("----------------------------------------");
            outputStream.write(new byte[]{1,2,3,4,5,6,7,8,0x09});
            outputStream.flush();
        }
        outputStream.close();
        inputStream.close();
        socket.close();
        server.close();
    }
}
