Connection to the database too slow

Question

I don’t know what happened that now the connection to the database is taking too long. Before I was quick to give the answer if it was connected or not... now it takes about 15 minutes and my pc doesn’t work right gets everything mainly locking the eclipse...

Now any project gives this "bug"... I wonder where I’m going wrong?

The connector I’m using is this, I’ve tried the current also gave in the same... mysql-Connector-java-5.0.8-bin-jar

package br.com.Sistema.dal;

import java.sql.*;
public class ModuloConexao {
    //metodo por estabelecer conexao com o banco
    public static Connection conector() {
        java.sql.Connection conexao = null;

        // linha abaixo "chama" o driver
        String driver = "com.mysql.jdbc.Driver";

        // armazenando informaçoes referente ao bd
        String url = "jdbc:mysql://localhost:3306/teste";
        String user = "root";
        String pass = "vertrigo";

        // Estabecendo conexao ao Banco de Dados
        try {
            Class.forName(driver);
            conexao = DriverManager.getConnection(url, user, pass);
            System.out.println(conexao);
            return conexao;
        } catch (Exception e) {
            // a linha abaixo serve de apoio para esclarecer o erro
            //JOptionPane.showMessageDialog(null,"Não há Conexao com o Banco de Dados");
            return null;

        }


    }
}

        btnLogin.setBounds(92, 101, 176, 23);

    }
}

The code is working, only hangs at the time of connection to bank... I gave up my server, which is the vertrigo, installed again, did not work. I’ve installed Xampp too, didn’t work anyway...

Whatever is causing this error?
