用j2me写了一个电子白板，终端同时使用模拟器和手机。手机上绘图时在模拟器上显示很快，但是在模拟器上绘图时手机上显示很慢。
不知道什么原因，指点一下吧！

应该再说的详细一些，比如是如何传递图像的，可以贴一点代码出来。。。

手机的速度当然没有电脑快了
还有,传输的数据也没有那么实时啊

connectServer（）用来连接服务器
public void drawReceive()用来接收数据
        public void connectServer(){
        try{
    SocketConnection connection = (SocketConnection)Connector.open("socket://59.64.158.197:"+SERVER_PORT);
            connection.setSocketOption(SocketConnection.KEEPALIVE, 5);
            connection.setSocketOption(SocketConnection.DELAY, 0);
            connection.setSocketOption(SocketConnection.LINGER, 0);
            io_in = connection.openDataInputStream();
            io_out = connection.openDataOutputStream();

        }catch(IOException ioe){
            ioe.printStackTrace();
        }
        myClass.connected = true;
    }
    public void drawReceive(){
        while(myClass.connected){
            try{
                DataBag dataBag = new DataBag(0,0,0,0,0,true,0);
                dataBag.color = io_in.readInt();
                dataBag.sX = io_in.readInt();
                dataBag.sY = io_in.readInt();
                dataBag.eX = io_in.readInt();
                dataBag.eY = io_in.readInt();
                dataBag.commandCenter = io_in.readInt();
                dataBag.received = true;
                myClass.commandCenter(dataBag,dataBag.commandCenter);
            }catch(IOException ioe){
                ioe.printStackTrace();
                myClass.exit();
            }
        }
    }
