1. 安装

下载: http://dev.mysql.com/downloads/mysql/5.1.html

这是MYSQL 5.1版本自带的工具. 所以你装完5.1后就可以用了.

在安装过程中,你可能会遇到关于libmysqlclient.so.16的错误.

2. 使用

# 帮助
mysqlslap --help

常用的选项：
--concurrency 代表并发数量，多个可以用逗号隔开，当然你也可以用自己的分隔符隔开，这个时候要用到--delimiter开关。
--engines 代表要测试的引擎，可以有多个，用分隔符隔开。
--iterations 代表要运行这些测试多少次。
--auto-generate-sql 代表用系统自己生成的SQL脚本来测试。
--auto-generate-sql-load-type 代表要测试的是读还是写还是两者混合的（read,write,update,mixed）
--number-of-queries 代表总共要运行多少次查询。每个客户运行的查询数量可以用查询总数/并发数来计算。比如倒数第二个结果2=200/100。
--debug-info 代表要额外输出CPU以及内存的相关信息。
--number-int-cols 代表示例表中的INTEGER类型的属性有几个。
--number-char-cols 意思同上。
--create-schema 代表自己定义的模式（在MySQL中也就是库）。
--query 代表自己的SQL脚本。
--only-print 如果只想打印看看SQL语句是什么，可以用这个选项。

3. 测试

#测试环境
PowerEdge 1950 / 单盘 /10G MEM
OS: RHEL 5.3
MySQL版本为5.1.40
innodb_buffer_pool_size=2G
innodb_additional_mem_pool_size = 100M
innodb_max_dirty_pages_pct = 10
key_buffer_size=320M
bulk_insert_buffer_size = 64M
sync_binlog=0

#简单的测试结果:

对MYISAM, 如果只作插入操作, 相当于 40000条/秒
对INNODB, 如果只作插入操作, 相当于 15000条/秒
