Performance of Inserting Rows with a PreparedStatement

This section describes how to measure the performance of inserting rows using a PreparedStatement object.

Running SQL statements using PreparedStatement objects is supposed to be faster than using regular Statement objects. To test this, I wrote the following Java program to measure the performance of inserting rows using a PreparedStatement object into an empty table:

/* OraclePerformancePreparedStatement.java
 - Copyright (c) 2015, HerongYang.com, All Rights Reserved.
 */
import java.sql.*;
public class OraclePerformancePreparedStatement {
  public static void main(String [] args) {
    Connection con = null;
    try {
      oracle.jdbc.pool.OracleDataSource ds 
        = new oracle.jdbc.pool.OracleDataSource();
      ds.setDriverType("thin");
      ds.setServerName("localhost");
      ds.setPortNumber(1521);
      ds.setDatabaseName("XE");
      ds.setUser("Herong");
      ds.setPassword("TopSecret");
      con = ds.getConnection();

// Delete all rows from the table
      Statement sta = con.createStatement();
      sta.executeUpdate("DELETE FROM Profile");

// Start the test
     int count = 10000;
     long t1 = System.currentTimeMillis();

// PreparedStatement to insert rows
      PreparedStatement ps = con.prepareStatement(
	"INSERT INTO Profile (ID, FirstName, LastName)"
	+ " VALUES (?, ?, ?)");
      java.util.Random r = new java.util.Random();
      for (int i = 0; i < count; i++) {
      	ps.setInt(1,i+1);
      	ps.setString(2,Integer.toHexString(r.nextInt(9999)));
      	ps.setString(3,Integer.toHexString(r.nextInt(999999)));
        ps.executeUpdate();
      }      
      ps.close();

// End the test
     long t2 = System.currentTimeMillis();
     System.out.println("PreparedStatement insert "+count
         +" rows with "+(t2 -t1) +" milliseconds");

      con.close();        
    } catch (Exception e) {
      e.printStackTrace();
    }
  }
}

Here is the result on a Windows 7 system with a 2.5GHz processor, running JDK 1.8, Oracle 11.2 and odbc6.jar:

PreparedStatement insert 10000 rows with 22574 milliseconds

As a comparison, here is the result on a Windows XP system with a 997MHz processor, running JDK 1.6, Oracle 10.2 and odbc14.jar:

PreparedStatement insert 10000 rows with 7843 milliseconds

I am disappointed that the newer versions of computer, JDK, Oracle server and JDBC driver run about 2.9 times slower!
