SysBench Configuration

The OLTP test mode emulates real database usage by issuing common SQL queries on typical table structures. SysBench populates the following table with oltp-table-size rows at the beginning of the test.

CREATE TABLE `sbtest` (

`id` int(10) unsigned NOT NULL auto_increment, `k` int(10) unsigned NOT NULL default '0', `c` char(120) NOT NULL default '',

`pad` char(60) NOT NULL default '', PRIMARY KEY (`id`),

KEY `k` (`k`)

) ENGINE=InnoDB DEFAULT CHARSET=latin1

To test general purpose database performance, the complex test mode was used. The InnoDB storage engine supports ACID compliant transactions; therefore, the SysBench uses BEGIN/COMMIT statements around each of the transactions. Table 3 lists the SQL queries used in testing.

Table 3 SQL Queries

Type of Query	SQL Query Syntax
Point queries	SELECT c FROM sbtest WHERE id=N
Range queries	SELECT c FROM sbtest WHERE id BETWEEN N and M
Range SUM()	SELECT SUM(c) FROM sbtest WHERE id BETWEEN N AND M
queries
Ordered range	SELECT c FROM sbtest WHERE id BETWEEN N AND M ORDER BY c
queries
Distinct range	SELECT DISTINCT c FROM sbtest WHERE id BETWEEN N AND M ORDER BY c
queries
Updates on	UPDATE sbtest SET k=k+1 WHERE id=N
indexed column
Updates on	UPDATE sbtest SET c=N WHERE id=N
non-index column
Delete queries	DELETE FROM sbtest WHERE id=N
Insert queries	INSERT INTO sbtest VALUES (...)

Table 4 lists the configuration options that were used for SysBench.
