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:
/* MySqlPerformanceRegularStatement.java * Copyright (c) HerongYang.com. All Rights Reserved. */ import java.util.*; import java.sql.*; import javax.sql.*; public class MySqlPerformanceRegularStatement { 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(); // 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))+"')"); } rs.close(); // End the test long t2 = System.currentTimeMillis(); System.out.println("Regular Statement 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 Connector/J 8.0.19:
Regular Statement insert 10000 rows with 3348 milliseconds
Here is summary of performance results on this program in the past with different versions of storage engine, MySQL, Java, and JDBC driver:
Operation: Regular INSERT Execution Storage MySQL Java JDBC Computer CPU Time (ms) Engine Server Version Driver System GHz --------- ------- ------ ------- ------ ------- --- 3348 MyISAM 8.0 13 8.0 macOS 10 2.6 915 MyISAM 5.5 8 5.1 Windows 7 2.5 922212 InnoDB 5.5 8 5.1 Windows 7 2.5 1297 MyISAM 5.0 6 5.0 Windows XP 1.0
As you can see, MySQL and JDBC driver 8.0 is much slower than MySQL and JDBC driver 5.5. Why? Maybe macOS 10 is slower than Windows 7?
