Sending values to BD makes the application too slow

Question

I created a program in java to capture the movement of a sensor and then send the data to a database, so that later the movement is accessed by another machine in real time (or almost) elsewhere. the movement is captured perfectly, the data is sent, and the other machine can read the data at the time the data is updated in the database. The problem is that when I start sending the data to the database, the program becomes extremely slow, with a delay of more than 6 seconds, not only in sending, but in everything.

The code that reads and sends is as follows::

public static ScheduledExecutorService StartPrintFrames (final Device device)
{
    isPrinting = true;
    isPaused = false;
    final ScheduledExecutorService ses = Executors.newSingleThreadScheduledExecutor();
    ses.scheduleAtFixedRate(new Runnable() {
        @Override
        public void run() {
            try {
                int[] x = new int[4];
                x = methods.GetFrame(device);
                tela.AtualizeBar(x[0],x[1],x[2],x[3]);
                tela.AtualizeHeartRate(x[3]);
                //ConnectionToDB.instance.SendFrames(x[0],x[1],x[2],x[3]);
                } 
            catch (BPException ex) 
            {
                Logger.getLogger(Classe.class.getName()).log(Level.SEVERE, null, ex);
            }
        }
    }, 0, 1, TimeUnit.MILLISECONDS);
    printFrames = ses;
    return ses;
}

The way it is it does not send the values to the BD, because the line below is commented, so the program runs without any delay, but when this line discovers the program is extraordinarily slow

//ConnectionToDB.instance.SendFrames(x[0],x[1],x[2],x[3]);

The Sendframes() method is as follows:

public void SendFrames(int v1, int v2, int v3, int v4)
{
    try
    {
        //frame 1,2,3,4
        String request = "UPDATE Tabela SET ent1 = ?, ent2 = ?, ent3 = ?, ent4 = ?;";
        PreparedStatement pst = connection.prepareStatement(request);
        pst.setInt(1,v1);
        pst.setInt(2,v2);
        pst.setInt(3,v3);
        pst.setInt(4,v4);
        pst.execute();
    } 
    catch (Exception e)
    {
        System.out.println(e);
    }
}

Can someone give me a light on how to solve this or another way to send the data that does not give this whole Leg?
