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:
/* OraclePerformanceRegularStatement.java
- Copyright (c) 2015, HerongYang.com, All Rights Reserved.
*/
import java.sql.*;
public class OraclePerformanceRegularStatement {
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();
// Regular Statement to insert rows
Statement rs = con.createStatement();
java.util.Random r = new java.util.Random();
for (int i = 0; i < count; i++) {
rs.executeUpdate(
"INSERT INTO Profile (ID, FirstName, LastName) VALUES ("
+(i+1)+", '"+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) {
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:
Regular Statement insert 10000 rows with 63897 milliseconds
Comparing with PreparedStatement, regular Statement performs much slower than PreparedStatement, see the table below:
Operationg System: Windows 7 CPU speed: 2.5GHz JVM version: 1.8.0_45 Oracle Server: 11.2 JDBC driver: ojdbc6.jar Statement # of inserts Time in ms. Comparison PreparedStatement 10000 22574 100% Regular Statement 10000 63897 279%
As a comparison, here is the result of OraclePerformanceRegularStatement.java on a Windows XP system with a 997MHz processor, running JDK 1.6, Oracle server 10.2 and ojdbc14.jar, which was actually faster:
Regular Statement insert 10000 rows with 13609 milliseconds
