MySQL性能测试工具sysbench
sysbench是一款开源的多线程性能测试工具，可以执行CPU/内存/线程/IO/数据库等方面的性能测试。数据库目前支持MySQL/Oracle/PostgreSQL。本文只是简单演示一下几种测试的用法，后续准备利用sysbench来对MySQL进行一系列的测试。具体的一些参数设置，需要根据不同的测试要求来进行调整。
下载
编译安装
默认支持MySQL，如果需要测试Oracle/PostgreSQL，则在configure时需要加上–with-oracle或者–with-pgsql参数

CPU测试
sysbench采用寻找最大素数的方式来测试CPU的性能

文件IO性能测试
首先生成需要的测试文件，文件总大小300M，16个并发线程，随机读写模式。执行完后会在当前目录下生成一堆小文件。

MySQL数据库测试
首先需要创建默认的sbtest数据库,或者使用–mysql-db指定一个已经存在的数据库
生成测试数据，引擎为myisam,表大小为1000000条记录
