常用参数

 1 –concurrency #代表并发数量，多个可以用逗号隔开。例如：–concurrency=50,200,500
 2 –engines #代表要测试的引擎，可以有多个，用分隔符隔开。例如：–engines=myisam,innodb,memory
 3 –iterations #代表要在不同并发环境下，各自运行测试多少次。
 4 –auto-generate-sql #代表用mysqlslap工具自己生成的SQL脚本来测试并发压力。
 5 –auto-generate-sql-add-auto-increment #代表对生成的表自动添加auto_increment列，从5.1.18版本开始，
 6 –auto-generate-sql-load-type #代表要测试的环境是读操作还是写操作还是两者混合的（read,write,update,mixed）
 7 –number-of-queries #代表总共要运行多少条查询。
 8 –debug-info #代表要额外输出CPU以及内存的相关信息。
 9 –number-int-cols #代表示例表中的INTEGER类型的属性有几个。
