Simple socket server and client, to test the speed of java socket

Client.java

import java.io.InputStream;
import java.net.Socket;

public class SimpleClient {

	public static void main(String[] args) throws Exception {
		Socket socket = new Socket("127.0.0.1", 6666);
		InputStream input = socket.getInputStream();
		long total = 0;
		long start = System.currentTimeMillis();

		byte[] bytes = new byte[10240]; // 10K
		while (true) {
			int read = input.read(bytes);
			total += read;
			long cost = System.currentTimeMillis() - start;
			if (cost > 0 && System.currentTimeMillis() % 10 == 0) {
				System.out.println("Read " + total + " bytes, speed: " + total / cost + "KB/s");
			}
		}
	}

}

Server.java

import java.io.OutputStream;
import java.net.ServerSocket;
import java.net.Socket;

public class SimpleServer {
	public static void main(String[] args) throws Exception {
		ServerSocket server = new ServerSocket(6666);
		Socket socket = server.accept();
		OutputStream output = socket.getOutputStream();

		byte[] bytes = new byte[10 * 1024]; // 10K
		for (int i = 0; i < bytes.length; i++) {
			bytes[i] = 12;
		}

		while (true) {
			output.write(bytes);
		}
	}
