Hi, I have a simple program to insert 10,000 records into a table. It runs very fast at the very beginning. But it becomes slower and slower after a while. To insert 10000 record it costs more than one hour. What is the best way to do that? Thanks.

public void loadT3Slip() {
  for (int i = 0; i < 10000; i++) {
    T3Slip t3slip = new T3Slip();
    t3slip.setXXX1(xxx);
    t3slip.setYYY(yyy);
    ......
    entityManager.persist(t3slip);
  }
}
