Hibernate花费太长时间插入表格10至15秒？

Question

其实我是hibernate的新手我已经在hibernate中编写了一个简单的程序，需要大约10到15秒才能执行，我的代码有些问题请帮忙。

import org.apache.log4j.BasicConfigurator;
import org.hibernate.Session;  
import org.hibernate.SessionFactory;  
import org.hibernate.Transaction;  
import org.hibernate.cfg.Configuration;  
public class StoreData 
{
    public static void main(String[] args) 
    {
        BasicConfigurator.configure();
        Configuration  cfg = new Configuration();
        cfg.configure("hibernate.cfg.xml");
        SessionFactory factory=cfg.buildSessionFactory();  
        Session session=factory.openSession();  
        Transaction t=session.beginTransaction();  

        Employee e1=new Employee();   
        e1.setFirstName("ABC");  
        e1.setLastName("DEF"); 

        Employee e2=new Employee();   
        e2.setFirstName("HIJ");  
        e2.setLastName("KLM");      

        session.persist(e1);
        session.persist(e2);

        t.commit();  

        session.close();  

        System.out.println("successfully saved");  
    }

}
