Hi!
A person compared the performances of MySQL, MaxDB, PostgreSQL, and
Oracle, and posted his result at
http://laser.dyndns.pgsqldb.com/index.php?rid=1923&S=aeac79693ab902121ccb13957fb65d8c&t=msg&...
I excerpted his JBuilder benchmark testing script and the results as
follows. Peronally I am not satisfied with PostgreSQL's position in the
result, which shows that PostgreSQL is only faster than MySQL4.1. Can
anyone give some comments on this? Should we ignore all of them?
Regards,
CN

Tested platform: WinXP SP1
public void testInsert()
{
java.sql.Connection conn = null;
try {
//MYSQL4.1
conn = java.sql.DriverManager.getConnection(
"[url]jdbc:mysql://localhost:3333/test[/url]");
test("MySQL4", conn);
//MYSQL5
conn =
java.sql.DriverManager.getConnection("[url]jdbc:mysql://localhost/test[/url]");
test("MySQL5", conn);
//MAXDB
conn = java.sql.DriverManager.getConnection(
"[url]jdbc:sapdb://LOCALHOST/TEST?unicode=true[/url]",
"USERTEST", "USERTEST");
test("MAXDB", conn);
// postgresql
conn = java.sql.DriverManager.getConnection(
"[url]jdbc:postgresql://localhost:5432/testdb[/url]", "user",
"1234");
test("POSTGRESQL", conn);
//ORACLE
conn = java.sql.DriverManager.getConnection(
"jdbc:oracle:thin:@127.0.0.1:1521:mydb", "ssdb", "ssdb");
test("ORACLE", conn);
}
catch (Exception e) {
e.printStackTrace();
}
}
public void test(String db,java.sql.Connection conn) throws Exception
{
try
{
java.sql.Statement st = conn.createStatement();
try {
try
{
st.executeUpdate("drop table dm");
}catch(Exception e)
{
;
}
st.execute("Create Table dm(id integer,mc varchar(40))");
}
finally {
st.close();
}
java.util.Date d_first = new java.util.Date();
System.out.println("");
System.out.print(db);
System.out.print(" now will start :");
System.out.println(d_first.getTime());
conn.setAutoCommit(false);
java.sql.PreparedStatement pst = conn.prepareStatement(
"insert into dm(id,mc) values(?,?)");
for (int i = 0; i < 10000; i++) {
pst.setInt(1, i);
pst.setString(2, "benchmark test");
pst.execute();
}
conn.rollback();
java.util.Date d_last = new java.util.Date();
System.out.print(db);
System.out.print(" now END:");
System.out.println(d_last.getTime());
System.out.print(db);
System.out.print(" Use Time ¡G");
System.out.println(d_last.getTime() - d_first.getTime());
}finally
{
conn.close();
}
}
The result follows (figures are in seconds):
MySQL4 Use Time ¡G13484
MySQL5 Use Time ¡G9703
MAXDB Use Time ¡G10641
POSTGRESQL Use Time ¡G11547
ORACLE Use Time ¡G11140
Replacing ROLLBACK with COMMIT in the testing script he got the
following result:
MySQL4 Use Time ¡G14031
MySQL5 Use Time ¡G9937
MAXDB Use Time ¡G10985
POSTGRESQL Use Time ¡G12860
