性能测试工具sysbench简介
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
./configure --prefix=/u01/sysbench \--with-mysql-includes=/opt/mysql/include/mysql \--with-mysql-libs=/opt/mysql/lib/mysqlmake && make install参数

CPU测试
sysbench采用寻找最大素数的方式来测试CPU的性能
NinGoo:/u01/sysbench/bin>$sysbench --test=cpu --cpu-max-prime=2000 runsysbench 0.4.12:multi-threaded system evaluation benchmarkRunning the test with following options:Number of threads: 1Doing CPU performance benchmarkThreads started!Done.Maximum prime number checked in CPU test: 2000Test execution summary: total time: 2.3996s total number of events: 10000 total time taken by event execution: 2.3917 per-request statistics: min: 0.23ms avg: 0.24ms max: 27.44ms approx.95 percentile: 0.24msThreads fairness: events (avg/stddev): 10000.0000/0.00 execution time (avg/stddev): 2.3917/0.00线程测试

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。

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
