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:

/* MySqlPerformancePreparedStatement.java
 * Copyright (c) HerongYang.com. All Rights Reserved.
 */
import java.util.*;
import java.sql.*;
import javax.sql.*;
public class MySqlPerformancePreparedStatement {
  public static void main(String [] args) {
    Connection con = null;
    try {
      com.mysql.cj.jdbc.MysqlDataSource ds
        = new com.mysql.cj.jdbc.MysqlDataSource();
      // com.mysql.jdbc.jdbc2.optional.MysqlDataSource ds
      //   = new com.mysql.jdbc.jdbc2.optional.MysqlDataSource();

      ds.setServerName("localhost");
      ds.setPortNumber(3306);
      ds.setDatabaseName("HerongDB");
      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 (FirstName, LastName) VALUES (?, ?)");
      Random r = new Random();
      for (int i = 0; i < count; i++) {
        ps.setString(1,Integer.toHexString(r.nextInt(9999)));
        ps.setString(2,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) {
      System.err.println("Exception: "+e.getMessage());
      e.printStackTrace();
    }
  }
}

Here is the result on a macOS system with a 2.6 GHz processor, running JDK 13, MySQL 8.0.17 and MySQL Connnector/J 8.0.19:

PreparedStatement insert 10000 rows with 4373 milliseconds

As a reference, here is the result on a Windows 7 system with a 2.5GHz processor, running JDK 1.8, MySQL 5.5 and MySQL Connnector/J 5.1.36:

PreparedStatement insert 10000 rows with 945810 milliseconds

I am very surprised to see that MySQL 5.5 is so slow to insert rows, about 100 milliseconds to insert 1 row!

As a reference, here is the result on a Windows XP system with a 997MHz processor, running JDK 1.6, MySQL 5.0 and MySQL Connnector/J 5.0.7:

PreparedStatement insert 10000 rows with 1281 milliseconds

So why is MySQL 5.5 is so slow comparing to MySQL 5.0? The next tutorial will give some explanation.
