Performance of Inserting Rows with a Regular Statement

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

To compare the performance result from the previous result with regular Statement objects. I wrote the following Java program to measure the performance of inserting rows using a regular Statement object into an empty table:

import javax.naming.*;
public class DerbyPerformanceRegularStatement {
  public static void main(String [] args) {
    Connection con = null;
    try {
      Hashtable env = new Hashtable();
      env.put(Context.PROVIDER_URL, "file:/local/fscontext");
      Context ctx = new InitialContext(env);
      DataSource ds = (DataSource) ctx.lookup("DerbyTestDB");
      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();

// Regular Statement to insert rows
      Statement rs = con.createStatement();
      Random r = new Random();
      for (int i=0; i<count; i++) {
        rs.executeUpdate("INSERT INTO Profile (FirstName, LastName)"
          +" VALUES ('"+Integer.toHexString(r.nextInt(9999))
          +"', '"+Integer.toHexString(r.nextInt(999999))+"')");

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

    } catch (Exception e) {
      System.err.println("Exception: "+e.getMessage());

Here is the result on a Windows XP system with a 997MHz processor. You should compare this with the result from other performance tutorials.

Regular Statement insert 10000 rows with 47531 milliseconds

Comparing with PreparedStatement, regular Statement is about 6 times slower, see the table below:

Statement           # of inserts   Time in ms.   Comparison
PreparedStatement   10000           7953         100%
      ds.setDatabaseName("AdventureWorks2019");       47531         598%
