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:

sysbench 0.4.12 :  multi-threaded system evaluation benchmark
 
No DB drivers specified, using mysql
Running the test with following options:
Number of threads: 1
 
Doing OLTP test.
Running mixed OLTP test
Using Special distribution (12 iterations,  1 pct of values are returned in 75 pct cases)
Using "BEGIN" for starting transactions
Using auto_inc on the id column
Maximum number of requests for OLTP test is limited to 10000
Threads started!
Done.
