南京爱尚天地:Mysql 性能测试

Mysql 性能测试 sysbench是一个模块化的、跨平台、多线程基准测试工具，主要用于评估测试各种不同系统参数下的数据库负载情况。关于这个项目的详细介绍请看：http://sysbench.sourceforge.net。
它主要包括以下几种方式的测试：
1、cpu性能
2、磁盘io性能
3、调度程序性能
4、内存分配及传输速度
5、POSIX线程性能
6、数据库性能(OLTP基准测试)
目前sysbench主要支持 MySQL,pgsql,oracle 这3种数据库。

测试参数: 对myisam存储引擎

指定表最大记录数为 1000000 Sysbench --test=oltp --mysql-table-engine=myisam --oltp-table-size=1000000 --mysql-socket=/tmp/mysql.sock --mysql-user=test --mysql-host=192.168.1.77 --mysql-password=test run

测试结果如下:
