Sysbench的安装请参考http://blog.csdn.net/mchdba/article/details/8951289
1 CPU测试
sysbench采用寻找最大素数的方式来测试CPU的性能

[root@xx sysbench-0.4.12]# sysbench --test=cpu --cpu-max-prime=2000 run

sysbench 0.4.12:  multi-threaded system evaluation benchmark

Running the test with following options:

6 MySQL数据库测试 select
首先需要创建默认的test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innodb,表大小为30000000条记录
6.1 准备数据
--oltp-test-mode

报错如下:

7.4 总结
--oltp-nontrx-mode=STRING       mode for non-transactional test {select, update_key, update_nokey, insert, delete} [select]
--max-requests=N           limit for total number of requests [10000]
如果这里不指定--max-requests,默认为10000,就是执行1W次操作就结束了,如果要做压力测试的话,就需要手动设置此值。
--num-threads=N            number of threads to use [1] (clients to access mysql db)
这里指的是有多少个mysql clents来访问mysql服务器,用show full processlist就可以看到大概的记录数。

7.5 接下来重新压力测试,设置2000W request测试。

录入测试数据 2000W

报这个错误,是因为数据没有,7.8.1没有执行,需要重新录入测试数据。

7.8.2测试结果稍后补上,后台正在运行中......

MySQL基准测试---sysbench

- - 博客园_首页
 一、 在对网站整体性能进行benchmark时,可以使用多种工具,比如大名鼎鼎的ab(Apache bench),http_load等工具. 这里我们不关注他们的使用,如果你想了解,可以去 这里.   重点来说MySQL的基准测试如何进行,也有很多种工具来供我们选择,比如mysqlslap、sysbench、Super Smack等,其中mysqlslap的使用MySQL官网给出了介绍,Super Smack是服务器压力测试强有力的工具,那么sysbench便是我们进行MySQL基准测试的很漂亮的工具了.

sysbench测试MySQL服务器性能(cpu,io,内存,mysql等)

- - CSDN博客数据库推荐文章
Sysbench的安装请参考http://blog.csdn.net/mchdba/article/details/8951289. sysbench采用寻找最大素数的方式来测试CPU的性能. 首先生成需要的测试文件,文件总大小1000M,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 5.6 online ddl 测试

- - CSDN博客数据库推荐文章
     在生产环境中,因为业务需求,改动mysql表结构,特别是数据量特别大的时候,几百万甚至几千万的数据,mysql online ddl操作非常让mysql dba揪心. 5.6版本支持online ddl.    为什么mysql ddl操作让dba揪心呢. 因为mysql ddl操作内部原理是这样的:.

MySQL 5.6.17/Percona5.6.16/MariaDB 10.0.11/OneSQL 5.6.16 TpmC测试

- - MySQL中文网 - 叶金荣的技术和生活
近日花了点时间对几个分支版本进行对比测试,包括了:MySQL 5.6.17、Percona5.6.16、MariaDB 10.0.11、OneSQL 5.6.16. 测试工具: tpcc-mysql. 测试Warehouse数: 10/100. 并发线程数: 64 ~ 1920. 内核:2.6.32-358.el6.x86_64.

sysbench安装、使用、结果解读

- - MySQL中文网
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. 目前sysbench代码托管在launchpad上,项目地址: https://launchpad.net/sysbench(原来的官网 http://sysbench.sourceforge.net 已经不可用),源码采用bazaar管理.

MySQL 5.6 测试之 Replication(主从复制)

- - MySQL 中文网 -
MySQL 5.6测试之Replication. MySQL 5.6版本相比以前新增了很多令人激动的特性,简要介绍见: 转:MySQL 5.6新特性. 性能方面已经做过测试了,详细请见: MySQL 5.6 vs MariaDB 5.5 vs Percona(5.5 & 5.6) 之TPCC性能测试.

MySQL TPCH测试工具简要手册

- - MySQL 中文网 -
tpch是TPC(Transaction Processing Performance Council)组织提供的工具包. 用于进行OLAP测试,以评估商业分析中决策支持系统(DSS)的性能. 它包含了一整套面向商业的ad-hoc查询和并发数据修改,强调测试的是数据库、平台和I/O性能,关注查询能力.

Mysql压力测试shell脚本

- - CSDN博客数据库推荐文章
转载请注明,来自: http://blog.csdn.net/skyman_2001. Mysql自带了压力测试工具mysqlslap,所以我们可以不用自己编写程序来测试Mysql读取的压力. 上面脚本的意思是每隔100ms循环做这样的事:模拟100个mysql客户端,对数据库test的表test执行200次插入(number-of-queries = concurrency * 每个mysql客户端的查询次数,所以这里的每个mysql客户端的查询次数是2次),迭代10次.

MySQL Cluster-备份恢复初步测试

- - CSDN博客数据库推荐文章
在  http://blog.csdn.net/mchdba/article/details/10544585  的第八小节里面进行扩展测试. 8.1 sql节点上面录入数据:.  8.2 管理节点上面,开始备份.  8.3 再次插入几条数据(为了保持和正式环境尽可能接近,在插入数据中间穿插了flush logs操作!).

MySQL 5.6 vs MySQL 5.5 性能对比初步测试结果

- - ITeye博客
在MySQL 推出第一个5.6的GA版本后,我们对5.6进行了简单的性能对比测试. 测试的基本思路是在同一台服务器上(保证硬件环境完全一样),先后安装MySQL 5.6和5.5,使用sysbench工具进行同样的压力测试,对比结果. 服务器配置:8核CPU+16G内存的HP360服务器. 测试压力:sysbench的oltp的性能测试,测试表数据量5000万.
